Description

Technical Field

[0001] This utility model relates to a position adjustment device for vehicle interior parts and a vehicle. Background Technology

[0002] With the booming development of new energy vehicles, more and more vehicles are equipped with a large central control screen or display screen in the center of the dashboard, and the display screen integrates many functions. In order to allow the driver or passengers to view the screen at a comfortable angle, more and more car manufacturers are making the central control screen adjustable in position.

[0003] To better achieve the screen tilting function, the existing screen position adjustment device needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a position adjustment device for vehicle interior parts and a vehicle, which can solve at least one of the problems mentioned above.

[0005] To achieve the above objectives, this utility model proposes a position adjustment device for vehicle interior trim parts, characterized in that the position adjustment device comprises:

[0006] A housing that can be fixedly mounted relative to the vehicle body;

[0007] Two linear drive mechanisms are at least partially arranged in the housing. Each linear drive mechanism includes a fixed portion and a movable portion. The fixed portion is connected to the housing and cannot move linearly relative to the housing. The movable portion is connected to the fixed portion and can move linearly relative to the fixed portion in a first direction. The movable portion can be hinged to the vehicle interior trim.

[0008] A oscillating device is provided to the first linear drive mechanism of the two linear drive mechanisms, allowing the moving part of the first linear drive mechanism to oscillate in a second direction perpendicular to the first direction. However, the oscillating device is not provided to the second linear drive mechanism of the two linear drive mechanisms, so that the moving part of the second linear drive mechanism cannot oscillate in the second direction.

[0009] The technical effects here include: designing one linear drive mechanism to be swingable while setting the other linear drive mechanism to be non-swingable, which on the one hand can prevent jamming when deflecting the vehicle interior parts, and on the other hand can still achieve controllable and precise positioning of the vehicle interior parts during deflection.

[0010] Advantageously, the oscillating device includes a pivot hole and a pivot pin inserted into the pivot hole and capable of pivoting relative to the pivot hole. One of the pivot hole and the pivot pin is fixed relative to the first linear drive mechanism, while the other of the pivot hole and the pivot pin is fixed relative to the housing. The pivoting movement of the pivot pin in the pivot hole allows the moving portion of the first linear drive mechanism to oscillate relative to the housing in the second direction.

[0011] Advantageously, one of the pivot hole and pivot pin is provided by a bracket fixedly connected to the fixed portion of the first linear drive mechanism, and the rotational movement of the bracket relative to the housing allows the moving portion of the first linear drive mechanism to swing relative to the housing in the second direction.

[0012] Advantageously, the first linear drive mechanism is configured as a first lead screw drive mechanism, which includes a first link forming the moving part, a first motor assembly forming the fixed part, and a first lead screw threadedly connected to the first link on one side and connected to the first motor assembly on the other side. The first link can be driven to move linearly in the first direction by rotating the first lead screw driven by the first motor assembly. The bracket has a first section providing one of the pivot hole and the pivot pin and a second section fixedly connected to the first motor assembly.

[0013] Advantageously, the first section is supported on the inner side of the bottom or top wall of the housing and is rotatable relative to the inner side by pivoting of the pivot pin in the pivot hole.

[0014] Advantageously, the second section is disposed in a rear wall notch in the rear wall of the housing and spaced laterally from the rear wall, such that the second section does not interfere with the rear wall when the support rotates relative to the housing.

[0015] Advantageously, the first link passes through a front wall notch in the front wall of the housing and is spaced apart from the front wall by a lateral gap, such that the first link does not interfere with the front wall when it swings relative to the housing.

[0016] Advantageously, the bracket is disposed between the first motor assembly and the first connecting rod in its second section, and the second section of the bracket is provided with a clearance hole for the first lead screw to pass through.

[0017] Advantageously, the two linear drive mechanisms are each configured as lead screw drive mechanisms, each lead screw drive mechanism including a connecting rod that forms the moving part, a motor assembly that forms the fixed part, and a lead screw that is threaded to the connecting rod on one side and connected to the motor assembly on the other side. The motor assembly drives the lead screw to rotate, thereby driving the connecting rod to move linearly in the first direction.

[0018] Advantageously, at least one of the two links of the two linear drive mechanisms has a body portion that is hinged to a vehicle interior trim piece at its front end and threaded to a corresponding lead screw at its rear end via a threaded hole provided in the body portion. Furthermore, the body portion has a groove communicating with the threaded hole in front of the threaded hole, the groove extending from the side of the body portion toward the interior of the body portion, and the lead screw is able to enter the groove after passing through the threaded hole.

[0019] Advantageously, the front free end of the lead screw is in a groove during the linear motion of the at least one link.

[0020] To achieve the above objectives, the present invention also proposes a vehicle, characterized in that the vehicle includes a position adjustment device for vehicle interior trim according to the present invention and includes vehicle interior trim, wherein the two linear drive mechanisms of the position adjustment device are respectively hinged to the vehicle interior trim with their moving portions.

[0021] Advantageously, the vehicle interior trim is a central control screen, and the position adjustment device is capable of driving the central control screen to translate in the X direction and deflect around the Z direction. During the deflection movement of the central control screen, the oscillating device allows the central control screen to drive the moving part of the first linear drive mechanism to oscillate around the Z direction.

[0032] The following describes illustrative embodiments of the present invention. In this specification, various systems, structures, and devices are schematically depicted in the accompanying drawings for illustrative purposes only, and not all features of actual systems, structures, and devices are described. For example, well-known functions or structures are not described in detail to avoid unnecessary detail that could obscure the present invention. It should be understood that in any practical application, many specific implementation decisions need to be made to achieve the specific goals of the developer or user, and system-related and industry-related limitations need to be followed. These specific goals may vary depending on the practical application. Furthermore, it should be understood that while such implementation decisions are complex and time-consuming, they are routine tasks for those skilled in the art who will benefit from the present invention.

[0033] The terms and phrases used herein should be understood and interpreted in accordance with the understanding of those skilled in the art. The consistent use of terms or phrases herein is not intended to imply a specific definition, i.e., a definition different from the common and conventional meaning understood by those skilled in the art. For terms or phrases intended to have a specific meaning, i.e., a meaning different from that understood by those skilled in the art, such specific definition will be explicitly listed in the specification, giving the specific definition of the term or phrase directly and unambiguously.

[0034] Unless otherwise required by the content, throughout the following description, the word “including” and its variations, such as “comprising” and “having”, will be interpreted in an open-ended, inclusive sense, that is, as “including but not limited to”.

[0035] like Figure 1 As shown, the position adjustment device 1 for vehicle interior parts according to this utility model can be installed inside a vehicle V to adjust the position of the vehicle interior parts. Here, the XYZ three-dimensional vehicle body coordinate system commonly used by the vehicle V is established.

[0036] For example, a vehicle interior component can be the central control screen 2, but it should be understood that the vehicle interior component is not limited to the central control screen 2, and can also be other vehicle interior components that require position adjustment. For the central control screen 2, the position adjustment device 1 can adjust its position in the X direction and its position about the Z direction in the XY plane.

[0037] The position adjustment device 1 for vehicle interior trim parts according to this utility model may include two parallel linear drive mechanisms. Each linear drive mechanism may include a fixed part and a movable part that can reciprocate linearly relative to the fixed part. The movable part may be directly hinged to the vehicle interior trim part. The two linear drive mechanisms are independent of each other, so their movable parts can be adjusted independently, and together they achieve position adjustment of the vehicle interior trim parts.

[0038] When the moving parts of two linear drive mechanisms move forward to varying degrees to deflect vehicle interior trim components, to avoid interference between the two linear drive mechanisms, or their moving parts, and the vehicle interior trim components at the hinge points, one linear drive mechanism can be designed to be oscillating, while the other can be set to be non-oscillating. This allows for controllable and precise positioning of the vehicle interior trim components during position adjustment, especially during deflection. If both linear drive mechanisms are oscillating, the position adjustment of the vehicle interior trim components, particularly deflection, will be disadvantageously uncontrollable.

[0039] Each linear drive mechanism can be configured as any type of mechanism in which the moving part can move linearly relative to the fixed part, such as an electric cylinder-piston rod drive mechanism (the cylinder body is the fixed part and the piston is the moving part), a pneumatic cylinder-piston rod drive mechanism (the cylinder body is the fixed part and the piston is the moving part), and a lead screw drive mechanism or a lead screw-slider drive mechanism (the lead screw is the fixed part and the slider is the moving part), etc.

[0040] To ensure that the distance between the two hinged points of the two moving parts on the vehicle interior trim remains unchanged when the trim is rotated left or right, thus avoiding motion interference or jamming, one of the moving parts and its associated linear drive mechanism can be designed to swing at an angle via an equipped swinging device for distance compensation. The other moving part and its associated linear drive mechanism can be designed to be immobile to ensure controllable positioning of the vehicle interior trim.

[0041] The oscillating device may include one of a pivot pin and a pivot hole fixed relative to the linear drive mechanism, and the other of a pivot pin and a pivot hole fixed relative to the vehicle body. The desired oscillating motion of the linear drive mechanism relative to the vehicle body can be achieved by the engagement of the pivot pin in the pivot hole and the relative pivoting of the two.

[0042] The following description uses the central control screen 2 as an example of a vehicle interior component and the lead screw drive mechanism as an example of a linear drive mechanism to illustrate one embodiment of this utility model.

[0043] Figure 2a The schematic diagram shows a perspective view of the position adjustment device 1 according to an embodiment of the present invention from the motor side (hereinafter referred to as the rear side, which is the front side facing X-up in the installation state of the central control screen 2 in the vehicle V), on which the central control screen 2 is connected; Figure 2b schematically shown Figure 2a Exploded view of the position adjustment device 1 in the middle; Figure 3a schematically shown Figure 2a A perspective view of the position adjustment device 1 from the side of the central control screen (hereinafter referred to as the front side, which is the rear side facing X-axis when the central control screen 2 is installed in vehicle V), omitting the cover 14; and Figure 3b schematically shown Figure 3a An exploded view of the position adjustment device 1 in the middle.

[0044] See Figures 2a to 3b The position adjustment device 1 includes two parallel or (at least in the initial position) parallel lead screw drive mechanisms that function as linear drive mechanisms. Each lead screw drive mechanism includes connecting rods 3.1 and 3.2 (which are configured as the "moving part" described above), lead screws 4.1 and 4.2 that cooperate with connecting rods 3.1 and 3.2, and motor assemblies 5.1 and 5.2 that are fixedly connected to lead screws 4.1 and 4.2 and can drive lead screws 4.1 and 4.2 to rotate. Here, the two connecting rods 3.1 and 3.2, the two lead screws 4.1 and 4.2, and the two motor assemblies 5.1 and 5.2 are arranged in parallel in the Y direction, for example (at least in the initial position), facing each other. Each connecting rod 3.1 and 3.2 can be pivotally hinged to the central control screen 2 (see [reference]) directly via a pivot shaft 6 at its front end. Figure 2b), and is threadedly connected to and driven by lead screws 4.1 and 4.2 passing through its rear end. Therefore, the two motor assemblies 5.1 and 5.2 drive their respective connecting rods 3.1 and 3.2 on axes bb and aa (parallel to the X direction) by rotating their respective lead screws 4.1 and 4.2 (see...). Figure 3a and Figure 3b It moves forward or backward in a straight line, thereby driving the central control screen 2 to translate or deflect.

[0045] To enable threaded connection between connecting rods 3.1 and 3.2 and lead screws 4.1 and 4.2, internal threads are provided on connecting rods 3.1 and 3.2 to engage with the external threads of lead screws 4.1 and 4.2. Therefore, Figure 4a and Figure 4b Two configurations of the internal thread on connecting rods 3.1 and 3.2, and in this example, on the right connecting rod 3.2, are shown respectively.

[0046] exist Figure 4a In the first embodiment of the right link 3.2 shown, the right link 3.2 has a generally cuboid-shaped main body 7. The main body 7 can be hinged to the central control screen 2 at the front end via a hinge portion 16 and threadedly driven to the right lead screw 4.2 at the rear end. For this purpose, a threaded hole 8 with internal threads is provided, for example, centrally located at the rear end of the main body 7 of the right link 3.2. The right lead screw 4.2 with external threads can be screwed into the threaded hole 8 to drive the right link 3.2 to move in the X direction through the engagement of the internal and external threads. An elongated groove 9 communicating with the threaded hole 8 is provided in front of the threaded hole 8 on the main body 7 of the right link 3.2. This groove 9 can extend from one side 10 of the main body 7 (in the Y direction) into the interior of the main body 7 and can extend in the X direction over most of the length of the main body 7. Therefore, the right lead screw 4.2 can directly enter the groove 9 suspended after passing through the threaded hole 8 from the rear end of the right link 3.2. When the right lead screw 4.2 rotates to drive the right connecting rod 3.2 to move backward in a straight line relative to the right lead screw 4.2, the front end of the right lead screw 4.2 should always be spaced apart from the front wall 11 of the groove 9 to avoid motion interference or jamming. For example, in the initial position of the right connecting rod 3.2 in the retracted state, the free end of the lead screw is closest to the front wall 11 but still does not contact the front wall 11.

[0047] When manufacturing the right connecting rod 3.2, for example, a groove 9 can be milled from the side 10 of the main body 7 into the interior of the main body 7, and then a threaded hole 8 can be introduced from the rear end face of the main body 7 towards the groove 9 to communicate with the groove 9. Therefore, this combination of groove 9 and threaded hole 8 not only makes the structure compact, but also makes manufacturing more convenient.

[0048] It is conceivable that this design of the right connecting rod 3.2 in terms of the threaded hole 8 and the groove 9 would also apply to the left connecting rod 3.1, and will not be elaborated further here. For example, only the orientation of the groove 9 is reversed, that is, in the installed state, the respective grooves 9 of the left connecting rod 3.1 and the right connecting rod 3.2 are oriented open to each other, but this is not mandatory, that is, they can also be oriented in the same direction or opposite to each other in the installed state.

[0049] exist Figure 4b In the second embodiment of the right link 3.2 shown, the right link 3.2 has a generally cuboid body 7 as in the first embodiment, but additionally provides a connecting portion 12 fixedly connected to the body 7. Similarly, the body 7 can be hinged to the central control screen 2 at the front end via a hinge portion 16 and threadedly driven to the right link 3.2 at the rear end. For this purpose, the connecting portion 12 can protrude laterally from one side 10 of the rear of the body 7, for example, protruding towards the left link 3.1 in the installed state. The connecting portion 12 and the body 7 can be integrally formed, or they can be separately constructed and then fixed to each other. Here, the connecting portion 12 and the body 7 are flush with each other on their rear end faces. The thickness of the connecting portion 12 in the z-direction is less than that of the body 7, and it is centrally connected to the body 7 in the z-direction; therefore, the upper and lower sides of the connecting portion 12 are offset from the upper and lower sides of the body 7, respectively. The right connecting rod 3.2 has a threaded hole 8 with internal threads on its connecting part 12 and passes through the connecting part 12. The right lead screw 4.2 with external threads can be screwed into the threaded hole 8 to drive the right connecting rod 3.2 to move linearly in the X direction through the internal and external thread engagement.

[0050] Similarly, this design of the connecting part 12 and threaded hole 8 of the right link 3.2 also applies to the left link 3.1, and will not be repeated here. For example, only the orientation of the connecting parts 12 is opposite, that is, in the installed state, the respective connecting parts 12 of the left link 3.1 and the right link 3.2 are oriented towards each other, but this is not mandatory, that is, they can also be oriented in the same direction or opposite to each other in the installed state.

[0051] In the position adjustment device 1 of this embodiment, both connecting rods 3.1 and 3.2 adopt... Figure 4a The linkage design shown according to the first embodiment is more compact due to the absence of the laterally extending connecting portion 12. In other embodiments of the position adjustment device 1, both linkages 3.1 and 3.2 can adopt... Figure 4b The linkage design shown according to the second embodiment can also be configured such that one of the two linkages 3.1 and 3.2 is arranged as follows: Figure 4a The first embodiment shown is designed accordingly, while the other is designed according to... Figure 4b The second embodiment shown is designed accordingly.

[0052] The position adjustment device 1 also includes a housing for partially accommodating the lead screw drive mechanism. The housing comprises a box body 13 below, which forms the lower part of the first housing portion, and a cover 14 above, which forms the upper part of the second housing portion. The plate-shaped cover 14 is connected from above to the box body 13 by screws 15 to cover it. The box body 13 and the entire housing can be fixedly connected to the vehicle body to remain relatively stationary. The cover 14 and the box body 13 together define a receiving cavity in which the two connecting rods 3.1 and 3.2 can be at least largely accommodated. Here, the connecting rods 3.1 and 3.2 are movable between an initial position where they are at least largely, essentially completely, within the receiving cavity and an extended limit position where they are largely moved forward out of the receiving cavity, thereby adjusting the position of the central control screen 2.

[0053] like Figure 3a As shown, in the initial position, links 3.1 and 3.2 can extend substantially along the entire length of the housing, with only their front hinged portions 16 located outside the housing for connection to the external central control screen 2. Meanwhile, the rear ends of links 3.1 and 3.2 remain within the housing or enclosure 13 during their movement.

[0054] To ensure that the distance L between the two hinged parts 16 of the connecting rods 3.1 and 3.2 on the central control screen 2 does not change when the central control screen 2 is tilted left or right (see... Figure 5b To avoid motion interference or jamming, one of the links 3.1 and 3.2 and its associated lead screw drive mechanism can be designed to swing in the Y direction in the XY plane for distance compensation.

[0055] In this embodiment, the left link 3.1 and its associated left lead screw drive mechanism are designed to be swingable, while the right link 3.2 and its associated right lead screw drive mechanism are designed to be non-swingable. It is also conceivable that in some embodiments, the right link 3.2 and its associated right lead screw drive mechanism are designed to be swingable, while the left link 3.1 and its associated left lead screw drive mechanism are designed to be non-swingable. The maximum threshold of the swing angle of the swingable link 3.1 or 3.2 can be determined based on the maximum deflection angle required by the central control screen 2. The larger the maximum deflection angle required by the central control screen 2, the larger the maximum threshold of the swing angle of the swingable links 3.1 and 3.2 should be designed to be, in order to meet the distance compensation requirements; that is, the two are positively correlated. For example, the maximum threshold of the swing angle of the swingable links 3.1 and 3.2 can be designed to be between 1° and 3°, which can meet the compensation for the deflection angle typically required by the central control screen 2.

[0056] See Figures 2a to 3bThe position adjustment device 1 also includes a swinging device for the left lead screw drive mechanism, which allows the left connecting rod 3.1 to swing relative to the housing during linear motion relative to the left lead screw 4.1, for example, when the left connecting rod 3.1 is subjected to a Y-direction lateral force applied to it by the central control screen 2. See [link to relevant documentation] Figure 5b When the front hinge points 16 of the two links 3.1 and 3.2 are not misaligned in the X direction, the two links 3.1 and 3.2 are parallel to each other and spaced apart by a Y-direction distance L. When the front hinge points 16 of the two links 3.1 and 3.2 are misaligned in the X direction, the rigid central control screen 2 will still maintain the distance L between the two front hinge points 16. Therefore, the swingable left link 3.1 swings its front hinge point 16 toward the right link 3.2 by a compensation angle, while the right link 3.2 does not swing in this way to ensure the controllable positioning of the central control screen 2.

[0057] In this embodiment, see Figure 3b The swinging device may include a pivot hole 17 fixed relative to the left lead screw drive mechanism and a pivot pin 18 fixed relative to the vehicle body, housing or box 13. The desired swinging motion of the left lead screw drive mechanism relative to the vehicle body or housing can be realized by the engagement of the pivot pin 18 in the pivot hole 17 and the relative pivoting of the two.

[0058] Here, the pivot hole 17 of the oscillating device can be provided or formed by a bracket 19 (in this embodiment, L-shaped), specifically a horizontal section 20 of the bracket 19, which can rest parallel to the inner surface of the bottom wall 21 of the housing. Corresponding to the pivot hole 17, a pivot pin 18 is fixedly provided, for example, integrally formed, on the inner surface of the bottom wall 21 of the housing, which extends vertically toward the lid 14 from the inner surface. Thus, see... Figure 3b The bracket 19 can rotate relative to the housing 13 around an axis cc parallel to the Z direction, thereby enabling the entire screw drive mechanism fixedly connected to the bracket 19 to swing relative to the housing 13 around the axis cc.

[0059] In some embodiments, the pivot pin 18 of the oscillating device may be provided or formed on the horizontal section 20 of the bracket 19, while a pivot hole 17 is provided on the inner side of the bottom wall 21 of the housing.

[0060] In some embodiments, one of the pivot pin 18 and pivot hole 17 of the oscillating device may be provided or formed thereon by a horizontal section 20 of the bracket 19, while the other of the pivot pin 18 and pivot hole 17 may be provided or formed thereon by a cover 14 (or the top wall of the housing). That is, both housing portions of the housing, here the housing 13 and the cover 14, can be used to provide one of the pivot pin 18 and pivot hole 17 of the oscillating device, while the other is provided by the bracket 19.

[0061] The bracket 19 may have a vertical section 22 that is fixedly connected to, for example, integrally formed with, and extends, for example, perpendicular to the horizontal section 20. This vertical section 22 may be fixedly connected to the fixed portion of the linear drive mechanism, in this case, the left motor assembly 5.1, for example, by screws 23, to pivotally support the left motor assembly 5.1 and thus the entire left lead screw drive mechanism on the housing 13. A clearance hole 24 is provided on the vertical section 22 for the left lead screw 4.1 to pass through. After passing through the clearance hole 24 through the vertical section 22 in front of it, the left lead screw 4.1 continues to pass into the threaded hole 8 of the left connecting rod 3.1 in front of the vertical section 22. Thus, the vertical section 22 is positioned between the left motor assembly 5.1 and the left connecting rod 3.1 (see [reference]). Figure 3a This makes the entire structure very compact. Additionally, the L-shaped bracket 19 is easy to manufacture and install, saving costs.

[0062] The vertical section 22 of the bracket 19 can be positioned in the square rear wall notch 25 of the rear wall 24 of the housing 13 in the installed state. Here, the thickness of the vertical section 22 in the X direction can be substantially equal to the thickness of the rear wall 24 of the housing 13, so that the vertical section 22 of the bracket 19 can be arranged substantially flush with the rear wall 24 of the housing 13 in the Y direction, or can be formed as part of the rear wall 24, thereby saving material.

[0063] The width of the vertical section 22 in the Y direction can be less than the width of the rear wall notch 25 so that the vertical section 22 is spaced apart from the housing in the Y direction, that is, spaced apart laterally from the remaining part of the rear wall 24 of the housing that defines the rear wall notch 25 and the side wall 26 of the housing. This ensures that the vertical section 22 will not interfere with or get stuck with the housing when the central control screen 2 deflects, driving the lead screw drive mechanism and thus the bracket 19 swings relative to the housing, allowing for distance compensation when the central control screen 2 deflects. Similarly, a front wall notch 28 is provided on the front wall 27 of the housing for the left connecting rod 3.1 to pass through. The width of the main body 7 of the left connecting rod 3.1 in the Y direction should also be less than the width of the front wall notch 28 so that the left connecting rod 3.1 is spaced apart from the housing or the front wall 27 of the housing in the Y direction, allowing the left connecting rod 3.1 to swing smoothly for distance compensation when the central control screen 2 deflects.

[0064] In addition, see Figure 3bA clearance groove 29 for the horizontal section 20 to be inserted can be provided at the lower rear end of the left link 3.1 so that the left link 3.1 can substantially abut against the vertical section 22 of the bracket 19 when it is in its initial position, making the structure more compact.

[0065] Furthermore, for the right link 3.2, which is designed for only linear motion, the width of the front wall notch 30 provided for the right link 3.2 on the front wall 27 of the housing can be substantially equal to the width of the right link 3.2, since it does not undergo oscillating motion. See also Figure 3a and Figure 3b In its initial position, the right connecting rod 3.2 can rest against the inner side of the rear wall 24 of the housing with its rear end face. The right motor assembly 5.2 is fixedly connected to the rear wall 24 of the housing 13 from the outside, for example by screws 23, so as to fix the right motor assembly 5.2 and the right lead screw 4.2 to the housing 13.

[0066] like Figure 2b , Figure 3b , Figure 4a and Figure 4b As shown, to guide the linear motion of the right connecting rod 3.2, a strip-shaped protrusion 31 extending in the X direction is provided on the lower side of its main body 7. The strip-shaped protrusion 31 extends substantially along the entire longitudinal direction of the main body 7. Correspondingly, a strip-shaped groove 32 extending in the X direction can be provided on the inner side of the bottom wall 21 of the housing 13. The strip-shaped groove 32 extends substantially along the entire longitudinal direction of the bottom wall 21 of the housing 13. Of course, it is also conceivable to reverse the arrangement, placing the strip-shaped protrusion 31 on the housing 13 and the strip-shaped groove 32 on the right connecting rod 3.2. The strip-shaped groove 32 can accommodate the strip-shaped protrusion 31, and the two are fitted with a small clearance in the width direction, i.e., in the Y direction. Thus, the right connecting rod 3.2 is both constrained by the housing 13 in the Y direction to wobble, and allowed to slide relative to the housing 13 in the X direction.

[0067] Figure 5a and Figure 5b The top view and the top view without the cover 14 are schematically shown to illustrate the position adjustment of the central control screen 2 by the position adjustment device 1 of this utility model.

[0068] Next, combine Figure 5a and Figure 5b Describe the movement and orientation of the central control screen 2 from the perspective of viewing from the motor side to the central control screen side.

[0069] from Figure 5a and Figure 5b The left image shows the HOME position, or initial position, of the central control screen 2, as well as the initial states of the two connecting rods 3.1 and 3.2. At this time, the central control screen 2 extends upward in the Y direction, and its position is closer to the housing.

[0070] With the help of the position adjustment device 1, the central control screen 2 can be adjusted from... Figure 5a and Figure 5b The initial position in the left figure moves forward in a straight line (without deflection) and extends to... Figure 5a and Figure 5b The center screen 2 is moved forward in the right-hand image to facilitate viewing by the occupants. At this time, the center screen 2 still extends upward in the Y direction, and its position is further away from the housing. For this purpose, two lead screw drive mechanisms can respectively drive their two connecting rods 3.1 and 3.2 to extend forward synchronously, thereby causing the center screen 2 to move forward linearly without deflection. Conversely, if the two lead screw drive mechanisms respectively drive their two connecting rods 3.1 and 3.2 to retract synchronously backward, the center screen 2 can be moved backward linearly, i.e., from... Figure 5a and Figure 5b The right-hand image in the middle of the diagram moves forward in a straight line back to the initial position shown in the left image. See also... Figure 5b During the linear motion of the central control screen 2, the distance L between the front hinge parts 16 of the two connecting rods 3.1 and 3.2 remains unchanged because of the linear motion only.

[0071] With the help of the position adjustment device 1, by extending the right link 3.2 further than the left link 3.1, the central control screen 2 can also be tilted to the left. Figure 5a and Figure 5b The leftward deflection position shown in the upper right figure deflects the central control screen 2 towards the passenger side so that the passenger's line of sight when viewing the central control screen 2 is perpendicular to the central control screen 2 and can see the central control screen 2 clearly. During the leftward deflection movement of the central control screen 2, the right link 3.2 moves only in a linear motion, while the left link 3.1 (and thus the entire left linear drive mechanism) is deflected at an angle towards the right link 3.2 by the Y-direction deflection torque applied by the central control screen 2 for distance compensation, so that the distance L between the front hinge portion 16 of the two links 3.1 and 3.2 remains constant.

[0072] With the help of the position adjustment device 1, by extending the left link 3.1 more than the right link 3.2, the central control screen 2 can also be tilted to the right. Figure 5a and Figure 5b The rightward deflection position shown in the lower right figure deflects the central control screen 2 towards the driver's side so that the driver's line of sight when viewing the central control screen 2 is perpendicular to the central control screen 2 and can see the central control screen 2 clearly. During the rightward deflection movement of the central control screen 2, the right link 3.2 also moves only in a straight line, and the left link 3.1 (and therefore the entire left linear drive mechanism) is also deflected at an angle towards the right link 3.2 by the Y-direction deflection torque applied by the central control screen 2 to compensate for the distance, so that the distance L between the front hinge parts 16 of the two links 3.1 and 3.2 remains constant.

[0073] Finally, it should be noted that the above embodiments are merely for understanding and explaining the present invention, and do not constitute a limitation on the scope of protection of the present invention. Those skilled in the art can make modifications or recombinations based on the above embodiments, and none of these modifications or recombinations depart from the scope of protection of the present invention.
