However, at present, most of the fixing methods of in-vehicle display terminals are directly fixed to the instrument panel in a single mode of horizontal or vertical screen. This form cannot achieve proportional and full-screen display when facing image resources such as pictures and videos of different specifications, and at the same time, it cannot take into account the personal usage habits of different occupants. In related technologies, the rotation range of some disclosed rotary in-vehicle display terminals is limited, and it is easy to block the view when rotating to some positions, and it is difficult to take into account the usage requirements of the driver and co-driver for the display terminal, so there is room for improvement.

[0058] Next, refer to Figures 1 - 15Describe an actuator 100 for adjusting a display terminal 1 according to an embodiment of the present invention. The actuator 100 is used to adjust the angle of the display terminal 1. For example, the display terminal 1 can be switched between a landscape screen and a portrait screen, or the display terminal 1 can be adjusted to other positions. Among them, the display terminal 1 can be a touch screen, or the display terminal 1 can also be a display panel installed on an instrument panel beam, etc.

[0059] As Figures 1 - 15 shown, the actuator 100 for adjusting the display terminal 1 according to an embodiment of the present invention includes: a power source, a guide member 63, a limiting member 62, and a driving mechanism.

[0060] The power source 75a is used to provide the power for driving the display terminal 1 to move. The driving mechanism is connected to the power source 75a. The driving mechanism is used to connect to the display terminal 1 and is adapted to drive the display terminal 1 to rotate so as to realize the angle adjustment of the display terminal 1.

[0061] The driving mechanism includes a rotating shaft, and the axis of the output end of the rotating shaft does not coincide with the axis of the input end of the rotating shaft.

[0062] In some embodiments, as Figure 16 shown, the extending direction of the rotating shaft 79 forms an acute angle (such as Figure 16 θ in) with the rotation axis of the rotating shaft 79. The extending direction of the rotating shaft 79 can be the length direction of the rotating shaft 79 or the direction where the axis of the rotating shaft 79 is located.

[0063] In some embodiments, the rotating shaft includes at least two sections that form an angle with each other. For example, the angle between the axes of the two sections of the rotating shaft is an acute angle, or the angle between the axes of the two sections of the rotating shaft is an obtuse angle, or the axes of the two sections of the rotating shaft are perpendicular to each other. In one embodiment, the rotating shaft includes a first section and a second section. The first section is connected to the second section. The end of the first section facing away from the second section is the input end of the rotating shaft, and the end of the second section facing away from the first section is the output end of the rotating shaft. The end of the second section facing away from the first section is connected to the display terminal 1. During the rotation of the rotating shaft, the second section rotates around the axis of the first section, that is, the end of the second section facing away from the first section rotates around the axis of the first section. Thus, the display terminal 1 rotates around the axis of the first section, and the geometric center of the display terminal 1 gradually moves during the rotation, thereby realizing the variable-center rotation of the display terminal 1, which is convenient for the occupant to adjust the display terminal 1 to the required position.

[0064] In some other embodiments, the rotation axis includes two parallel and spaced-apart segments. In one embodiment, the rotation axis includes a first segment and a second segment. Alternatively, the first segment and the second segment can also be connected by other segments. For example, the rotation axis includes a first segment, a second segment, and a third segment. The rotation axis rotates about the axis of the first segment, and the first segment and the second segment are connected by the third segment so that the axis of the first segment is parallel and spaced apart from the axis of the second segment. The axis of the third segment can be perpendicular, acute, or obtuse to the axis of the first segment. The first segment is connected to the power part of the driving mechanism. That is, when the rotation axis rotates, the second segment and the third segment both rotate about the axis of the first segment. Among them, the second segment is connected to the display terminal 1. In this way, the second segment drives the display terminal 1 to rotate about the axis of the first segment at the same time. The geometric center of the display terminal 1 gradually moves during the rotation. Thus, the display terminal 1 realizes variable-center rotation, which is convenient for switching the display terminal 1 from landscape mode to portrait mode. The movement of the geometric center of the display terminal 1 can facilitate the driver and the co-driver to view and use it.

[0065] In some embodiments, the driving mechanism includes a sliding mechanism 3 and a rotating mechanism 7. The sliding mechanism 3 is used to connect to the display terminal 1 to move the display terminal 1. The power source 75a is used to drive the display terminal 1 to rotate through the rotating mechanism 7. The power source 75a is used to drive the display terminal 1 to rotate through the rotating mechanism 7 and the sliding mechanism 3 is linked when the display terminal 1 rotates. The sliding mechanism 3 and the rotating mechanism 7 do not move independently. The movement of the sliding mechanism 3 depends on the torque output by the rotating mechanism 7. The power source 75a can be integrated into the rotating mechanism 7. The power source 75a can provide driving force to the rotating mechanism 7, which is convenient for installation and can reduce power transmission loss at the same time.

[0066] The sliding mechanism 3 is used to adjust the position of the display terminal 1 so that the display terminal 1 moves relative to the vehicle body. For example, Figure 2 As shown, the sliding mechanism 3 includes a first sliding part 31 and a second sliding part 32. The first sliding part 31 and the second sliding part 32 can slide relative to each other. In Figure 2 the embodiment shown, the first sliding part 31 includes a slide rail, and the second sliding part 32 includes a chute. The first sliding part 31 and the second sliding part 32 can be slidably matched through the slide rail and the chute. The first sliding part 31 is connected to the display terminal 1. For example, the first sliding part 31 is relatively fixed to the display terminal 1, that is, the first sliding part 31 and the display terminal 1 move synchronously. In this way, when the first sliding part 31 slides relative to the second sliding part 32, the display terminal 1 slides relative to the second sliding part 32. Thus, while the display terminal 1 slides relative to the second sliding part 32, the display terminal 1 moves relative to the vehicle body, which is convenient for realizing the position adjustment of the display terminal 1.

[0067] For example, Figures 1 - 2As shown, the guiding member 63 is relatively fixed to the first sliding portion 31. For example, the guiding member 63 is directly fixed to the first sliding portion 31, the guiding member 63 can be connected to the first sliding portion 31 through a threaded fastener, or both the guiding member 63 and the first sliding portion 31 are fixed to the same component. In this way, when the guiding member 63 moves, the first sliding portion 31 moves synchronously with the guiding member 63. Thus, both the display terminal 1 and the first sliding portion 31 move synchronously with the guiding member 63, and further the position adjustment of the display terminal 1 is realized.

[0068] The limiting member 62 is fixedly assembled relative to the rotating mechanism 7 and is fixedly assembled relative to the vehicle body. For example, the limiting member 62 is installed on the instrument panel beam of the vehicle body, or the limiting member 62 is installed on the vehicle body through other components, so that the limiting member 62 is relatively fixed to the vehicle body, and the guiding member 63 is in rolling cooperation with the limiting member 62, that is, the guiding member 63 is in rotational and translational cooperation with the limiting member 62 to drive the first sliding portion 31 and the second sliding portion 32 to slide relative to each other when the rotating mechanism works. It should be noted that when the guiding member 63 moves synchronously with the first sliding portion 31 and the display terminal 1, the guiding member 63 is always in stable contact with the limiting member 62 and moves relative to it. In this way, during the movement of the guiding member 63, there is an interaction force at the contact point between the guiding member 63 and the limiting member 62, so that the guiding member 63 can move relative to the limiting member 62, facilitating the rotation of the display terminal 1.

[0069] As Figures 1 - 2 As shown, the rotating mechanism 7 is used to drive the display terminal 1 to rotate, so as to facilitate the rotating mechanism 7 to drive the display terminal 1 to switch between a landscape screen and a portrait screen. The rotating mechanism 7 is suitable for being installed on the vehicle body, and the output end of the rotating mechanism 7 is connected to the second sliding portion 32. The output end of the rotating mechanism 7 can drive the second sliding portion 32 to rotate, that is, the driving force output by the output shaft can drive the second sliding portion 32 to rotate. At the same time, the second sliding portion 32 is connected to the first sliding portion 31. Thus, the first sliding portion 31 and the display terminal 1 rotate simultaneously with the second sliding portion 32. The output end of the rotating mechanism 7 drives the first sliding portion 31 and the second sliding portion 32 to slide relative to each other when the rotating mechanism 7 works, and further realizes the rotational adjustment of the display terminal 1.

[0070] The actuating mechanism is arranged such that when the rotating mechanism 7 works, the sliding mechanism 3 rotates, and the guiding member 63 rolls along the limiting member 62 to make the first sliding portion 31 and the second sliding portion 32 slide relative to each other, that is, the guiding member 63 moves relative to the limiting member 62 while rotating relative to it. In other words, the rotating mechanism 7 can indirectly drive the second sliding portion 32 and the first sliding portion 31 to rotate through the cooperation between the guiding member 63 and the limiting member 62. During the rotation of the second sliding portion 32 and the first sliding portion 31, as Figure 1As shown, the guide member 63 installed on the second sliding portion 32 is always in contact with the limiting member 62. The guide member 63 rotates synchronously with the first sliding portion 31, and the guide member 63 applies a force to the limiting member 62 at the contact point with the limiting member 62. It can be understood that the limiting member 62 is relatively fixed to the vehicle body, that is, the position and state of the limiting member 62 remain unchanged.

[0071] Thus, the reaction force of the limiting member 62 on the guide member 63 drives the relative sliding of the first sliding portion 31 and the second sliding portion 32. The limiting member 62 is relatively stationary with respect to the second sliding portion 32. The force of the limiting member 62 on the guide member 63 causes the guide member 63 and the first sliding portion 31 to slide relative to the second sliding portion 32 at the same time, that is, the first sliding portion 31 and the display terminal 1 both slide relative to the second sliding portion 32, realizing the position adjustment of the display terminal 1.

[0072] During this movement process, the second sliding portion 32, the display terminal 1 and the first sliding portion 31 are all driven to rotate by the rotating mechanism 7. The rotation center of the second sliding portion 32 remains unchanged all the time, but the rotation center of the first sliding portion 31 gradually changes during the relative sliding with the second sliding portion 32, that is, the geometric centers of the display terminal 1 and the first sliding portion 31 both change. Furthermore, the variable-center rotation of the display terminal 1 is realized. The overall structural layout of the actuator 100 is reasonable, with strong functionality and good practicability.

[0073] The actuator 100 is arranged such that when the rotating mechanism 7 works, the guide member 63 moves relative to the limiting member 62 along the length direction of the guide member 63, and the guide member 63 rotates around the limiting member 62, that is, the guide member 63 slides relative to the limiting member 62, and at the same time the guide member 63 rotates relative to the limiting member 62. Thus, the first sliding portion 31 and the second sliding portion 32 rotate relative to the vehicle body, and at the same time the first sliding portion 31 slides relative to the second sliding portion 32, facilitating the switching between the landscape and portrait screens of the display terminal 1.

[0074] The actuator 100 is arranged such that when the rotating mechanism 7 works, the center of the guide member 63 moves, that is, during the process of the guide member 63 moving relative to the limiting member 62, the center of the guide member 63 gradually changes, and the geometric centers of the first sliding portion 31 and the display terminal 1 both change. Thus, the center of the display terminal 1 deviates from the initial center of the display terminal 1 during the rotation process, and the display terminal 1 can realize variable-center rotation, facilitating the occupant to adjust the display terminal 1 to the required position, realizing the switching between the landscape and portrait screens of the display terminal 1, and improving the user experience.

[0075] According to the actuator 100 for adjusting the display terminal 1 in an embodiment of the present invention, the display terminal 1, the first sliding part 31, and the second sliding part 32 are driven to rotate relative to the vehicle body by the rotating mechanism 7. During the rotation of the display terminal 1, the first sliding part 31, and the second sliding part 32, the guide member 63 and the limiting member 62 are always in contact. The interaction force between the guide member 63 and the limiting member 62 can drive the relative sliding of the first sliding part 31 and the second sliding part 32. Thus, the switching between the landscape and portrait screens of the display terminal 1 can be realized. During the rotation of the display terminal 1, the geometric centers of the first sliding part 31 and the display terminal 1 gradually change, and the display terminal 1 realizes variable-center rotation to adjust the display terminal 1 to the position required by the occupant, facilitating the satisfaction of the usage requirements of different occupants and improving the practicability of the display terminal 1.

[0076] As Figures 1 - 7 shown, in some embodiments, the guide member 63 includes a rack 63a, and the limiting member 62 includes a gear 62a. The rack 63a meshes with the gear 62a. Thus, through the cooperation of the rack 63a and the gear 62a, the planar compound motion of rotation and displacement between the guide member 63 and the limiting member 62 can be realized, facilitating the realization of variable-center rotation of the display terminal 1.

[0077] As Figures 1 - 7 shown, the actuator 100 includes: a sliding mechanism 3, a rack 63a, a gear 62a, and a rotating mechanism 7.

[0078] The sliding mechanism 3 is used to adjust the position of the display terminal 1 so that the display terminal 1 moves relative to the vehicle body. As Figure 2 shown, the sliding mechanism 3 includes a first sliding part 31 and a second sliding part 32. The first sliding part 31 and the second sliding part 32 can slide relative to each other. In the Figure 2 embodiment shown, the first sliding part 31 includes a slide rail, and the second sliding part 32 includes a slide groove. The first sliding part 31 and the second sliding part 32 can be slidably matched through the slide rail and the slide groove. The first sliding part 31 is connected to the display terminal 1. For example, the first sliding part 31 is relatively fixed to the display terminal 1, that is, the first sliding part 31 and the display terminal 1 move synchronously. In this way, when the first sliding part 31 slides relative to the second sliding part 32, the display terminal 1 and the second sliding part 32 slide relative to each other. Thus, while the display terminal 1 slides relative to the second sliding part 32, the display terminal 1 moves relative to the vehicle body, facilitating the realization of the position adjustment of the display terminal 1.

[0079] As Figures 1 - 2As shown, the rack 63a is fixedly connected to the first sliding part 31. For example, the rack 63a is directly fixed to the first sliding part 31, or the rack 63a can be connected to the first sliding part 31 through a threaded fastener, or both the rack 63a and the first sliding part 31 are fixed to the same component. In this way, when the rack 63a moves, the first sliding part 31 moves synchronously with the rack 63a. Thus, both the display terminal 1 and the first sliding part 31 move synchronously with the rack 63a, and further the position adjustment of the display terminal 1 is realized.

[0080] In one embodiment, as Figures 1 - 2 shown, the extending direction of the rack 63a is parallel to the sliding direction of the sliding mechanism 3, that is, the rack 63a is arranged in parallel with the first sliding part 31 and the second sliding part 32. When the first sliding part 31 and the second sliding part 32 slide relative to each other, the rack 63a moves synchronously and in the same direction as the first sliding part 31, which is convenient for the installation of the rack 63a and the sliding mechanism 3, prevents interference between the rack 63a and the first sliding part 31, makes the relative sliding between the display terminal 1 and the second sliding part 32 easier to achieve, and the motion structure of the actuator 100 is more reasonable.

[0081] The gear 62a is fixedly assembled relative to the vehicle body. For example, the rack 63a is installed on the instrument panel beam of the vehicle body, or the gear 62a is installed on the vehicle body through other components, so that the gear 62a is relatively fixed to the vehicle body and the gear 62a meshes with the rack 63a. It should be noted that when the rack 63a moves synchronously with the first sliding part 31 and the display terminal 1, the rack 63a is always stably meshed with the gear 62a. In this way, during the movement of the rack 63a, there is a meshing force at the meshing point between the rack 63a and the gear 62a, and the rack 63a rotates relative to the axis of the gear 62a, which is beneficial to realizing the rotation of the display terminal 1.

[0082] As Figures 1 - 2 shown, the rotating mechanism 7 is used to drive the display terminal 1 to rotate. The rack 63 rotates around the rotation axis and the rack 63 is always meshed with the gear 62, so as to facilitate the rotating mechanism 7 to drive the display terminal 1 to switch between the landscape screen and the portrait screen. The rotating mechanism 7 is suitable for being installed on the vehicle body, and the output end of the rotating mechanism 7 is connected to the second sliding part 32. The output end of the rotating mechanism 7 can drive the second sliding part 32 to rotate, that is, the driving force output by the output shaft can drive the second sliding part 32 to rotate. At the same time, the second sliding part 32 is connected to the first sliding part 31. Thus, the first sliding part 31 and the display terminal 1 rotate simultaneously with the second sliding part 32, and further the rotational adjustment of the display terminal 1 is realized.

[0083] The actuator 100 is configured such that when the rotating mechanism 7 operates, the sliding mechanism 3 rotates, and the rack 63a rotates along the gear 62a to cause the first sliding portion 31 and the second sliding portion 32 to slide relative to each other. In other words, the rotating mechanism 7 can indirectly drive the rotation of the second sliding portion 32 and the first sliding portion 31 through the cooperation of the rack 63a and the gear 62a. During the rotation of the second sliding portion 32 and the first sliding portion 31, as Figure 1 shown, the rack 63a mounted on the first sliding portion 31 is always engaged with the gear 62a. The rack 63a rotates synchronously with the first sliding portion 31, and the rack 63a applies a force to the gear 62a at the engagement point with the gear 62a. It can be understood that the gear 62a is relatively fixed to the vehicle body, that is, the position and state of the gear 62a remain unchanged. Thus, the reaction force of the gear 62a on the rack 63a drives the relative sliding of the first sliding portion 31 and the second sliding portion 32. The rack 63a is relatively stationary with the first sliding portion 31, and the force of the gear 62a on the rack 63a causes the rack 63a and the first sliding portion 31 to slide relative to the second sliding portion 32 at the same time, that is, both the first sliding portion 31 and the display terminal 1 slide relative to the second sliding portion 32, realizing the position adjustment of the display terminal 1.

[0084] During this movement process, the second sliding portion 32, the display terminal 1, and the first sliding portion 31 are all driven by the rotating mechanism 7 to rotate. The rotation center of the second sliding portion 32 remains unchanged all the time, and the geometric center of the second sliding portion 32 only rotates around the rotation center. However, in addition to rotating around the rotation center, the geometric center of the first sliding portion 31 also undergoes translation during the relative sliding of the first sliding portion 31 and the second sliding portion 32, realizing a composite movement, that is, the geometric centers of the display terminal 1 and the first sliding portion 31 both move, that is, the geometric center of the display terminal 1 is not fixed, and thus realizing the variable-center rotation of the display terminal 1. The overall structural layout of the actuator 100 is reasonable, with strong functionality and good practicability.

[0085] According to the actuator 100 for adjusting the display terminal 1 of the embodiment of the present invention, the display terminal 1, the first sliding portion 31, and the second sliding portion 32 are driven by the rotating mechanism 7 to rotate relative to the vehicle body. And during the rotation of the display terminal 1, the first sliding portion 31, and the second sliding portion 32, the rack 63a and the gear 62a are always engaged, and the mutual force between the rack 63a and the gear 62a can drive the relative sliding of the first sliding portion 31 and the second sliding portion 32. Thus, the switching between the landscape and portrait orientations of the display terminal 1 can be realized, and during the rotation of the display terminal 1, the geometric centers of the first sliding portion 31 and the display terminal 1 gradually change, and the display terminal 1 realizes variable-center rotation to adjust the display terminal 1 to the position required by the occupant, facilitating the satisfaction of the usage needs of different occupants and improving the practicability of the display terminal 1.

[0086] An actuator 100 for adjusting a display terminal 1 according to an embodiment of the present invention, such as Figures 1 - 2 As shown, the axis of the gear 62a coincides with the axis of the output shaft of the rotating mechanism 7. Thus, the gear 62a can be coaxially installed with the rotating mechanism 7, reducing the installation process and facilitating the installation of the gear 62a and the rotating mechanism 7. Moreover, the rotation center of the first sliding part 31 is located on the axis of the gear 62a, and the rotation center of the second sliding part 32 is located on the axis of the output shaft of the rotating mechanism 7. The gear 62a meshes with the rack 63a, and the geometric center of the rack 63a changes as the meshing point changes, facilitating the driving force output by the rotating mechanism 7 to drive the first sliding part 31, the second sliding part 32 and the display terminal 1 to rotate, reducing the power consumption of the rotating mechanism 7, improving the transmission efficiency between the rotating mechanism 7 and the second sliding part 32, and realizing the variable-center rotation of the display terminal. The gear 62a and the output shaft of the rotating mechanism 7 are arranged coaxially, which is beneficial to the overall structure layout of the actuator 100, making the installation of each component of the actuator 100 compact and reducing the space occupied by the actuator 100.

[0087] Such as Figure 6 As shown, the axis of the output end of the rotating mechanism 7 is spaced apart from the geometric center of the display terminal 1, that is, the rotating mechanism 7 is offset-mounted relative to the display terminal 1. The rotating mechanism 7 is used to drive the display terminal 1 to rotate from the initial position to the target position. For example, when the display terminal 1 is in the initial position, it is in the portrait orientation, and when it is in the target position, it is in the landscape orientation.

[0088] For example, in one embodiment, when the display terminal 1 is in the portrait orientation, the rotation center of the display terminal 1 is located on the axis of the output end of the rotating mechanism 7, the rotation center of the display terminal 1 is below the geometric center of the display terminal 1, the rack 63 is to the left of the gear 62, and the meshing point of the gear 62 and the rack 63 is to the left of the axis of the output end of the rotating mechanism 7. Thus, during the process of the display terminal 1 rotating from the initial position to the target position, the geometric center of the display terminal 1 rotates to the left around the rotation center of the display terminal 1, that is, the position of the geometric center of the display terminal 1 gradually changes.

[0089] During this process, the rack 63 and the gear 62 move relative to each other, and the rack 63 rotates downward around the gear 62. When the rack 63 and the display terminal 1 rotate 90° around the rotation center, the meshing point of the rack 63 and the gear 62 is below the axis of the output end of the rotating mechanism 7, and the rack 63 is below the gear 62. Thus, the geometric center of the rack 63 moves from the left of the gear 62 to below the gear 62, that is, the geometric center of the rack 63 moves downward and to the right, and the display terminal 1 and the rack 63 are relatively stationary during the rotation, that is to say, the geometric centers of the rack 63 and the display terminal 1 both move downward and to the right.

[0090] In this way, the display terminal 1 realizes the switching from the vertical screen to the horizontal screen. During the rotation process, the position of the geometric center of the display terminal 1 gradually changes, that is, the display terminal 1 realizes the rotation with a changing center, achieving the relative rotation and relative movement between the display terminal 1 and the vehicle body, facilitating the adjustment of the display terminal 1 to be close to the driver's seat or the co-driver's seat, and enhancing the practicality of the display terminal 1.

[0091] In some embodiments, the geometric center of the display terminal 1 in the initial position and the geometric center of the display terminal 1 in the target position are located on the same vertical line. For example, when the display terminal 1 is in the vertical screen state, the geometric center of the display terminal 1 can be located in the middle of the driver's cab and the co-driver's cab. When the display terminal 1 moves from the vertical screen state to the horizontal screen state, the geometric center of the display terminal 1 can still be located in the middle of the driver's cab and the co-driver's cab. When the display terminal 1 is in the horizontal screen state, the geometric center of the display terminal 1 can be located between the driver and the co-driver. When the display terminal 1 moves from the horizontal screen state to the vertical screen state, the geometric center of the display terminal 1 can still be located between the driver and the co-driver. In this way, the position of the display terminal 1 after movement can be located in the middle of the users at the driver's and co-driver's seats, facilitating the simultaneous viewing and use by the users at the driver's and co-driver's seats. Moreover, the display terminal 1 will not cause the geometric center to move horizontally due to position adjustment, so that the display terminal 1 will not interfere with the layout, installation, and use of the components arranged on the left and right sides of the display terminal 1, reducing the space occupied by the position adjustment of the display terminal 1, facilitating the design of the overall structure inside the vehicle, and improving the rationality of the design of the actuator 100.

[0092] In one embodiment, as Figure 7 shown, the lower edges of the display terminal 1 in the initial position and the target position are flush. In this way, when the display terminal 1 is in the horizontal screen or vertical screen state, the lower part of the display terminal 1 does not interfere with the layout and installation of other components, reducing the space occupied by the position adjustment of the display terminal 1, facilitating the design of the overall structure inside the vehicle, and improving the rationality of the design of the actuator 100.

[0093] In some embodiments, as Figures 1 - 2As shown, the actuator 100 also includes a fixed shaft 5, which is fixedly assembled relative to the vehicle body, and the gear 62a is fixedly connected to the fixed shaft 5. In this way, the gear 62a, the fixed shaft 5 and the vehicle body are connected as a whole, so that the gear 62a and the fixed shaft 5 are relatively fixed to the vehicle body, which is convenient for installing various components of the actuator 100, so that when the first sliding part 31, the second sliding part 32 and the display terminal 1 rotate, the gear 62a can stably support the force of the rack 63a, which is convenient for driving the first sliding part 31 and the second sliding part 32 to slide relative to each other, and realize the rotation of the display terminal 1. Therefore, the gear 62a is stably fixed to the vehicle body through the fixed shaft 5, which is convenient for realizing the relative sliding of the first sliding part 31 and the second sliding part 32, and then realizing the non-fixed center rotation of the display terminal 1, which is beneficial to improve the practicality of the actuator 100.

[0094] like Figures 2 - 3 As shown, the actuator 100 also includes an axial limit member 54, and the fixed shaft 5 includes a smooth rod segment 51, a circumferential limit segment 52 and an axial limit segment 53 connected in sequence, that is, one end of the circumferential limit segment 52 is connected to the smooth rod segment 51, and the other end of the circumferential limit segment 52 is connected to the axial limit segment 53, and the smooth rod segment 51 is fixedly assembled relative to the vehicle body. For example, a flange 55 is axially provided at the end of the smooth rod segment 51 away from the circumferential limit segment 52, and the flange 55 is provided with a plurality of threaded holes. The flange 55 can be connected to the vehicle body by threaded fasteners, or the flange 55 is connected to other components and fixed to the vehicle body together, so as to facilitate fixing the fixed shaft 5 to the vehicle body as a whole, and then fixing the gear 62a to the vehicle body through the fixed shaft 5, so that the installation of the actuator 100 is more stable.

[0095] like Figure 2 As shown, the gear 62a is sleeved on the circumferential limiting section 52, and the circumferential limiting section 52 can limit the gear 62a circumferentially, that is, the gear 62a and the fixed shaft 5 have no relative rotation, and one end face of the gear 62a presses against the end face of the light rod section 51, the axial limiting member 54 is connected to the axial limiting section 53, and the axial limiting member 54 presses against the other end face of the gear 62a, so that the two end faces of the gear 62a press against the light rod section 51 and the axial limiting member 54 respectively, wherein the axial limiting member 54 cooperates with the axial limiting section 53, and then stably fixes the gear 62a to the circumferential limiting section 52, so that the gear 62a and the fixed shaft 5 are relatively fixed in the axial and circumferential directions, so as to facilitate the relative sliding of the first sliding part 31 and the second sliding part 32 through the gear 62a, thereby ensuring the structural stability of the actuator 100.

[0096] Among them, Figure 3As shown, the circumferential limit section 52 has a polygonal cross section, that is, the outer peripheral wall of the circumferential limit section 52 can be a polygonal column or a polygonal pyramid, the gear 62a has a mounting hole 61, the mounting hole 61 is axially through, and the mounting hole 61 has a polygonal cross section, the mounting hole 61 is sleeved on the circumferential limit section 52, and the mounting hole 61 is suitable for cooperating with the circumferential limit section 52 to relatively fix the gear 62a and the fixed shaft 5 along the circumferential direction. It should be noted that, as Figure 3 As shown, the diameters of the light rod segment 51, the circumferential limit segment 52 and the axial limit segment 53 decrease successively, that is, the diameter of the circumferential limit segment 52 is smaller than that of the light rod segment 51, the diameter of the axial limit segment 53 is smaller than that of the circumferential limit segment 52, and the diameter of the mounting hole 61 is larger than that of the axial limit segment 53, and the diameter of the mounting hole 61 is smaller than that of the light rod segment 51. In this way, the gear 62a passes through the axial limit segment 53 and is then installed in the circumferential limit segment 52, and the axial limit member 54 is installed from one end of the axial limit segment 53 away from the circumferential limit segment 52, thereby fixing the gear 62a between the axial limit segment 53 and the light rod segment 51, thereby fixing the gear 62a and facilitating installation and disassembly.

[0097] like Figure 3 As shown, the axial limiting section 53 is an external thread section, and the axial limiting member 54 includes a nut. Therefore, after the gear 62a is installed from the axial limiting section 53, the nut is screwed and installed from the end of the axial limiting section 53 away from the circumferential limiting section 52. The nut can fix the gear 62a and the fixed shaft 5 axially to prevent the gear 62a from escaping from the circumferential limiting section 52, and to avoid the relative rotation of the gear 62a and the fixed shaft 5 to affect the meshing effect of the gear 62a and the rack 63a, thereby ensuring the stability and safety of the actuator 100, and facilitating the relative sliding of the display terminal 1 and the first sliding portion 31.

[0098] The rotating mechanism 7 has a first avoidance hole, which penetrates axially, and the fixed shaft 5 penetrates the first avoidance hole. Therefore, the rotating mechanism 7 is installed on the fixed shaft 5 and then installed on the vehicle body, so that the connection between the rotating mechanism 7 and the fixed shaft 5 is more compact, saving installation space, facilitating the overall layout of the actuator 100, reducing the overall occupied space of the actuator 100, and improving the overall performance of the actuator 100.

[0099] A bearing (not shown in the figure) is provided between the fixed shaft 5 and the rotating mechanism 7, that is, the rotating mechanism 7 can slide relative to the fixed shaft 5 through the bearing. Among them, the inner wall of the first avoidance hole of the rotating mechanism 7 is fixedly connected to the outer ring of the bearing, and the outer peripheral wall of the fixed shaft 5 is fixedly connected to the inner ring of the bearing. For example, the outer peripheral wall of the smooth rod section 51 is fixedly connected to the inner ring of the bearing. Thus, when the inner ring and the outer ring of the bearing rotate relative to each other, the rotating mechanism 7 rotates relative to the fixed shaft 5. In this way, the rotating mechanism 7 is installed on the fixed shaft 5 through the bearing, which facilitates the rotation of the rotating mechanism 7 to drive the display terminal 1, and at the same time facilitates the relative sliding between the first sliding part 31 and the display terminal 1. The overall layout of the actuator 100 is reasonable, the rotating mechanism 7, the fixed shaft 5 and other components are installed compactly, greatly improving the space utilization rate of the actuator 100, reducing the frictional loss of the relative rotation between the rotating mechanism 7 and the fixed shaft 5, and reducing the heat generated by friction.

[0100] In one embodiment, the fixed shaft 5 is a hollow shaft, that is, the fixed shaft 5 has a through hole extending in the circumferential direction. The circuit of the display terminal 1 can pass through the through hole of the fixed shaft 5, which is convenient for wiring, more suitable for the requirements of the overall vehicle mechanism with a compact space and a limited vehicle weight, and can also give users a better driving experience.

[0101] The actuator 100 for adjusting the display terminal 1 according to the embodiment of the present invention further includes: as Figures 1 - 2 shown, the first bracket 2, the second bracket 4, and the third bracket 8.

[0102] The first bracket 2 is used to mount the display terminal 1. As Figures 1 - 2 shown, the first bracket 2 is in the shape of a flat plate. The side of the first bracket 2 facing away from the first sliding part 31 is attached to the display terminal 1. Thus, when the first bracket 2 and the display terminal 1 are installed, they have a large contact surface, improving the stability of the installation of the display terminal 1. The first sliding part 31 is connected to the first bracket 2, and the first sliding part 31 and the first bracket 2 can be connected by threaded fasteners. For example, both the first sliding part 31 and the first bracket 2 are provided with threaded holes, and a bolt can be passed through the threaded holes to connect the first sliding part 31 and the first bracket 2. Moreover, the rack 63a is connected to the first bracket 2, and the rack 63a can be connected to the first bracket 2 by threaded fasteners. For example, the rack 63a is provided with a threaded hole for connecting to the first bracket 2, which is convenient for the relative fixation of the rack 63a and the first bracket 2.

[0103] In this way, the rack 63a and the first sliding part 31 are both stably fixed to the first bracket 2, and the display terminal 1 is relatively fixed to the first bracket 2, so that when the rotating mechanism 7 drives the first sliding part 31 and the second sliding part 32 to rotate, the first bracket 2 and the display terminal 1 rotate synchronously with the first sliding part 31, thereby ensuring that the various components of the actuator 100 are installed stably and fixed reasonably, and the overall structural layout is orderly, which is convenient for realizing the position adjustment of the display terminal 1 and completing the switching between the horizontal screen and the vertical screen of the display terminal 1, thereby improving practicality.

[0104] like Figures 1 - 2 As shown, the second bracket 4 is in the shape of a plate, and the second bracket 4 is connected to the second sliding part 32, for example, the second bracket 4 is connected to the second sliding part 32 by a threaded fastener, so that the second bracket 4 can move synchronously with the second sliding part 32, and the output end of the rotating mechanism 7 is connected to the second bracket 4, for example, the output end of the rotating mechanism 7 is connected to the second bracket 4 by a threaded fastener, thereby facilitating the driving force output by the rotating mechanism 7 to drive the second bracket 4 to rotate, thereby realizing the rotation adjustment of the first bracket 2 and the display terminal 1, and completing the switching of the horizontal screen and the vertical screen of the display terminal 1.

[0105] Among them, Figures 1 - 2 As shown, the second bracket 4 has a second avoidance hole 41, and the second avoidance hole 41 is axially penetrated. Figure 2 As shown, the fixed shaft 5 passes through the first avoidance hole and the second avoidance hole 41 in sequence, and after the fixed shaft 5 passes through the first avoidance hole and the second avoidance hole 41, the end of the fixed shaft 5 close to the display terminal 1 is fixedly connected to the gear 62a, so that it is convenient to install or disassemble the actuator 100, so that the rotating bracket, the second bracket 4 and the fixed shaft 5 are installed more compactly, which greatly saves the installation space of the actuator 100, reduces the overall occupied space of the actuator 100, improves the practicality of the actuator 100, and facilitates the installation and layout of the actuator 100.

[0106] The third bracket 8 is a fixed bracket of the actuator 100. The rotating mechanism 7 is mounted on the third bracket 8. The third bracket 8 is used to be fixedly connected to the vehicle body. The first bracket 2, the second bracket 4 and the display terminal 1 of the actuator 100 are all fixed to the vehicle body through the third bracket 8. Figures 1 - 2 As shown, the third bracket 8 is in the shape of a plate, and the fixed shaft 5 is installed on the third bracket 8, wherein the flange 55 of the bare rod section 51 is closely connected to the third bracket 8, so that the driving action of the rotating mechanism 7 on the display terminal 1 is stably supported, ensuring that the rotating mechanism 7 can accurately and effectively drive the display terminal 1 to rotate, thereby improving the rationality of the overall structure of the actuator 100.

[0107] like Figures 1 - 2As shown, the sliding mechanism 3 includes a plurality of members arranged in parallel at intervals. The plurality of sliding mechanisms 3 can stably support the relative sliding of the first bracket 2 and the second bracket 4, ensuring the stability of the relative sliding of the first bracket 2 and the second bracket 4. Moreover, sliding mechanisms 3 are provided on both sides of the rack 63a, that is, a plurality of sliding mechanisms 3 are respectively arranged on both sides of the rack 63a. For example, the sliding mechanism 3 includes two, and the two sliding mechanisms 3 are respectively distributed on both sides of the rack 63a. In this way, it is not only convenient for the overall layout of the sliding mechanism 3 and the rack 63a, but also can ensure that the first bracket 2 and the second bracket 4 can stably slide relative to each other, making the structural design of the actuator 100 more reasonable and reliable.

[0108] As Figures 8 - 15 shown, in some other embodiments, the guide member 63 includes a guide plate 63b, the guide plate 63b has a guide groove 64, the limiting member 62 includes a limiting pin 62b, and the limiting pin 62b is pivotally slidably engaged with the guide groove 64. Thus, through the cooperation of the guide plate 63b and the limiting pin 62b, a planar compound motion of rotation and displacement between the guide member 63 and the limiting member 62 can be realized, facilitating the realization of the variable-center rotation of the display terminal 1.

[0109] As Figures 8 - 15 shown, the actuator 100 for adjusting the display terminal 1 according to an embodiment of the present invention includes: a sliding mechanism 3, a guide plate 63b, a limiting pin 62b, and a rotating mechanism 7.

[0110] The sliding mechanism 3 is used to adjust the position of the display terminal 1 so that the display terminal 1 moves relative to the vehicle body. As Figure 9 shown, the sliding mechanism 3 includes a first sliding part 31 and a second sliding part 32, and the first sliding part 31 and the second sliding part 32 can slide relative to each other. In Figure 9 the embodiment shown, the first sliding part 31 includes a slide rail, the second sliding part 32 includes a slide groove, and the first sliding part 31 and the second sliding part 32 can be slidably engaged through the slide rail and the slide groove. The first sliding part 31 is connected to the display terminal 1. For example, the first sliding part 31 is relatively fixed to the display terminal 1, that is, the first sliding part 31 and the display terminal 1 move synchronously. In this way, when the first sliding part 31 slides relative to the second sliding part 32, the display terminal 1 and the second sliding part 32 slide relative to each other. Thus, while the display terminal 1 slides relative to the second sliding part 32, the display terminal 1 moves relative to the vehicle body, facilitating the adjustment of the position of the display terminal 1.

[0111] As Figures 8 - 9As shown, the guide plate 63b is fixedly relative to the first sliding part 31. For example, the guide plate 63b is directly fixed to the first sliding part 31, or the guide plate 63b can be connected to the first sliding part 31 through threaded fasteners, or both the guide plate 63b and the first sliding part 31 are fixed to the same component. In this way, when the guide plate 63b moves, the first sliding part 31 moves synchronously with the guide plate 63b. Thus, both the display terminal 1 and the first sliding part 31 move synchronously with the guide plate 63b, and further the position adjustment of the display terminal 1 is realized.

[0112] The limit pin 62b is fixedly assembled relative to the vehicle body. For example, the limit pin 62b is installed on the instrument panel beam of the vehicle body, or the limit pin 62b is installed on the vehicle body through other components to make the limit pin 62b relatively fixed to the vehicle body, such as Figure 11 As shown, the guide plate 63b has a guide groove 64, and the limit pin 62b is pivotally and slidably engaged with the guide groove 64. The limit pin 62b and the guide plate 63b can rotate relative to each other. It should be noted that when the guide plate 63b moves synchronously with the first sliding part 31 and the display terminal 1, the limit pin 62b rotates in the guide groove 64 and slides along the extension direction of the guide groove 64 in the guide groove 64. In this way, during the rotation of the guide plate 63b, the position of the limit pin 62b remains unchanged, and the mutual acting force between the inner wall of the guide groove 64 and the limit pin 62b causes the guide plate 63b and the limit pin 62b to slide relative to each other, that is, the limit pin 62b slides relative to the guide groove 64.

[0113] As Figures 8 - 9 As shown, the rotating mechanism 7 is used to drive the display terminal 1 to rotate, so as to realize that the rotating mechanism 7 drives the display terminal 1 to switch between landscape and portrait orientations. The rotating mechanism 7 is suitable for being installed on the vehicle body, and the output end of the rotating mechanism 7 is connected to the second sliding part 32. The output end of the rotating mechanism 7 can drive the second sliding part 32 to rotate, that is, the driving force output by the output shaft can drive the second sliding part 32 to rotate. At the same time, the second sliding part 32 is connected to the first sliding part 31. Thus, the first sliding part 31 and the display terminal 1 rotate simultaneously with the second sliding part 32, and further the rotational adjustment of the display terminal 1 is realized.

[0114] As Figures 13 - 15 As shown, the rotating mechanism 7 is used to drive the second sliding part 32 to rotate from the initial position to the target position. When the second sliding part 32 is in the initial position, the limit pin 62b is located at one end of the guide groove 64. When the second sliding part is in the target position, the limit pin is located at the other end of the guide groove 64. For example, when the initial position is when the display terminal 1 is in landscape orientation and the target position is when the display terminal 1 is in portrait orientation, that is, during the rotation of the display terminal 1 and the guide plate 63b, the limit pin 62b slides relative to the guide plate 63b in the guide groove 64, and the display terminal 1 slides relative to the second sliding part 32, which is convenient for realizing the position adjustment of the display terminal 1.

[0115] The actuator 100 is configured such that when the rotating mechanism 7 operates, the sliding mechanism 3 rotates, and the guide groove 64 and the limit pin 62b move relative to each other. The limit pin 62b is within the guide groove 64 and rotates relative to the guide plate 63b. The limit pin 62b slides relative to the guide plate 63b within the guide groove 64. In other words, the rotating mechanism 7 can indirectly drive the second sliding part 32 and the first sliding part 31 to rotate through the cooperation of the limit pin 62b and the guide plate 63b. During the rotation of the second sliding part 32 and the first sliding part 31, as Figure 9 shown, the limit pin 62b is located within the guide groove 64, the guide plate 63b rotates synchronously with the first sliding part 31, and the inner wall of the guide groove 64 of the guide plate 63b exerts a force on the limit pin 62b. It can be understood that the limit pin 62b is relatively fixed to the vehicle body, that is, the position and state of the limit pin 62b remain unchanged all the time. Thus, when the guide plate 63b rotates, there is a mutual force between the guide plate 63b and the limit pin 62b. The guide plate 63b and the first sliding part 31 are relatively stationary, and the force exerted by the limit pin 62b on the guide plate 63b drives the guide plate 63b and the first sliding part 31 to slide relative to the second sliding part 32, realizing the position adjustment of the display terminal 1.

[0116] During this movement process, the second sliding part 32, the first sliding part 31, and the display terminal 1 are all driven to rotate by the rotating mechanism 7. The rotation center of the second sliding part 32 remains unchanged all the time, and the geometric center only rotates around the rotation center. However, in addition to rotating around the rotation center, the geometric center of the first sliding part 31 also undergoes translation during the relative sliding process between the first sliding part 31 and the second sliding part 32, realizing a compound movement, that is, the geometric centers of the display terminal 1 and the first sliding part 31 both move, thereby realizing the variable-center rotation of the display terminal 1, that is, the geometric center of the display terminal 1 is not fixed and will change during the rotation process. The overall structural layout of the actuator 100 is reasonable, with strong functionality and good practicality.

[0117] As Figure 6 shown, the axis of the output end of the rotating mechanism 7 is spaced apart from the geometric center of the display terminal 1, that is, the rotating mechanism 7 is offset-mounted relative to the display terminal 1. As Figures 13 - 15 shown, the rotating mechanism 7 is used to drive the display terminal 1 to rotate from the initial position to the target position. At the initial position, the axis of the output end of the rotating mechanism 7 is in the first direction of the geometric center of the display terminal 1, and the axis of the limit pin 62 is in the second direction of the axis of the output end of the rotating mechanism 7. The first direction is perpendicular to the second direction. For example, the first direction is from top to bottom, and the second direction is from left to right or from right to left, and the display terminal 1 is set to rotate in the direction opposite to the second direction to rotate to the target position.

[0118] Among them, the rotation center of the display terminal 1 is located on the axis of the output end of the rotation mechanism 7, and the rotation center of the display terminal 1 is in the first direction of the geometric center of the display terminal 1. Thus, the geometric center of the display terminal 1 rotates around the rotation center of the display terminal 1 in the direction opposite to the second direction, that is, the position of the geometric center of the display terminal 1 gradually changes. During this process, the guide plate 63 and the limit pin 62 move relative to each other. The limit pin 62 moves from one end of the guide groove 64 to the other end, and the limit pin 62 rotates relative to the guide plate 63 within the guide groove 64. The mutual acting force between the guide plate 63 and the limit pin 62 drives the first sliding portion 31 to slide relative to the second sliding portion 32. Thus, through the cooperative movement of the guide plate 63 and the limit pin 62, the switching between the landscape and portrait orientations of the display terminal 1 can be achieved, and at the same time, the position of the geometric center of the display terminal 1 changes, realizing the variable-center rotation of the display terminal 1.

[0119] In one embodiment, when the display terminal 1 is in the portrait orientation, the axis of the output end of the rotation mechanism 7 is located below the geometric center of the display terminal 1, the rotation center of the display terminal 1 is located below the geometric center of the display terminal 1, the axis of the limit pin 62 is located to the right of the axis of the output end of the rotation mechanism 7, and the display terminal 1 is set to rotate leftward to achieve the landscape orientation.

[0120] As Figure 13 shown, at the initial position, the limit pin 62 is located at the right end of the guide groove 64, and the extending direction of the guide groove 64 is the same as the second direction. During the process of the display terminal 1 moving from the initial position to the target position, the geometric center of the display terminal 1 moves leftward around the axis of the output end of the rotation mechanism 7. At the same time, the end of the guide plate 63 away from the limit pin 62 rotates around the limit pin 62 in the first direction. The limit pin 62 gradually moves from one end of the guide groove 64 to the other end within the guide groove 64, the included angle between the extending direction of the guide groove 64 and the second direction gradually increases, and the included angle between the extending direction of the guide groove 64 and the first direction gradually decreases. For example, when the display terminal 1 is at the intermediate position between the initial position and the target position, the included angle between the extending direction of the guide groove 64 and the second direction is the same as the included angle between the extending direction of the guide groove 64 and the first direction. The structural design of the actuator 100 is reasonable to facilitate the further rotation of the display terminal 1 to achieve the switching between the landscape and portrait orientations.

[0121] And when the display terminal 1 moves to the target position, as Figure 15As shown, the limit pin 62 is located at the other end of the guide groove 64. The limit pin 62 is located at the lower end of the guide groove 64. The extending direction of the guide groove 64 is the same as the first direction. Among them, the distance between the geometric center of the guide plate 63 and the axis of the output end of the rotating mechanism 7 becomes larger. During the movement of the guide plate 63, the geometric center moves to the right. It is shown that the display terminal 1 moves synchronously with the guide plate 63. Thus, during the rotation of the display terminal 1, the geometric center of the display terminal 1 moves downward, and the distance between the geometric center of the display terminal 1 and the axis of the output end of the rotating mechanism 7 gradually becomes smaller. And in some embodiments, the geometric center of the display terminal 1 is located on the axis of the output end of the rotating mechanism 7, and the display terminal 1 switches to the landscape screen. In this way, the display terminal 1 realizes the switching from the portrait screen to the landscape screen, and during the rotation process, the position of the geometric center of the display terminal 1 changes gradually, that is, the display terminal 1 realizes variable-center rotation.

[0122] It can be understood that since the rotating mechanism 7 is offset-mounted relative to the display terminal 1, the torque output by the rotating mechanism 7 will cause the geometric center of the display terminal 1 to shift. By setting the guide plate 63 and the limit pin 62, the display terminal 1 undergoes translation on the basis of rotation. The shift of the geometric center of the display terminal 1 caused by the rotating mechanism 7 and the translation direction of the geometric center of the display terminal 1 caused by the limit pin 62 are exactly opposite. Thus, when the rotating mechanism 7 is in the initial position and the target position, the geometric center of the display terminal 1 is flush with the axis of the output end of the rotating mechanism 7 in the vertical direction.

[0123] In one embodiment, as Figure 7 shown, the lower edges of the display terminal 1 in the initial position and the target position are flush. In this way, when the display terminal 1 is in the landscape screen or the portrait screen, the lower part of the display terminal 1 does not interfere with the arrangement and installation of other components, reducing the space occupied by the position adjustment of the display terminal 1, facilitating the design of the overall structure inside the vehicle, and improving the rationality of the design of the actuator 100.

[0124] According to the actuator 100 for adjusting the display terminal 1 in the embodiment of the present invention, the rotating mechanism 7 drives the display terminal 1, the first sliding part 31 and the second sliding part 32 to rotate relative to the vehicle body. And during the rotation of the display terminal 1, the first sliding part 31 and the second sliding part 32, the limit pin 62b always presses against the inner wall of the guide groove 64 of the guide plate 63b. The interaction force between the guide plate 63b and the limit pin 62b can drive the first sliding part 31 and the second sliding part 32 to slide relative to each other. Thus, the switching between the landscape screen and the portrait screen of the display terminal 1 can be realized, and during the rotation of the display terminal 1, the geometric centers of the first sliding part 31 and the display terminal 1 change gradually, and the display terminal 1 realizes variable-center rotation to adjust the display terminal 1 to the position required by the occupant, facilitating the satisfaction of the usage requirements of different occupants and improving the practicability of the display terminal 1.

[0125] An actuator 100 for adjusting a display terminal 1 according to an embodiment of the present invention, such as Figures 8 - 9 shown, the axis of the limit pin 62b is parallel and spaced apart from the axis of the output shaft of the rotating mechanism 7, that is, the axis of the limit pin 62b does not coincide with the axis of the output end of the rotating mechanism 7, and the rotation center of the second sliding part 32 is located on the axis of the output end of the rotating mechanism 7. Thus, the relative movement between the limit pin 62b and the guide plate 63b causes the geometric center of the first sliding part 31 to gradually change as the guide plate 63b rotates, facilitating the driving force output by the rotating mechanism 7 to drive the first sliding part 31, the second sliding part 32 and the display terminal 1 to rotate, reducing the power consumption of the rotating mechanism 7, and enabling the display terminal 1 to perform variable-center rotation.

[0126] Such as Figures 8 - 9 shown, the actuator 100 further includes a fixed shaft 5 and a lever 65.

[0127] The fixed shaft 5 is fixedly assembled relative to the vehicle body, and the axis of the fixed shaft 5 coincides with the axis of the output end of the rotating mechanism 7. The limit pin 62b is fixedly connected to the fixed shaft 5. In this way, the limit pin 62b, the fixed shaft 5 and the vehicle body are connected as a whole, making the limit pin 62b and the fixed shaft 5 both relatively fixed to the vehicle body, facilitating the installation of each component of the actuator 100. When the first sliding part 31, the second sliding part 32 and the display terminal 1 rotate, the limit pin 62b can stably support the acting force of the guide plate 63b, facilitating the relative sliding between the first sliding part 31 and the second sliding part 32 to realize the rotation of the display terminal 1. Thus, the limit pin 62b is stably fixed to the vehicle body through the fixed shaft 5, facilitating the relative sliding between the first sliding part 31 and the second sliding part 32, and further realizing the variable-center rotation of the display terminal 1, which is beneficial to improving the practicability of the actuator 100.

[0128] The axis of the fixed shaft 5 coincides with the axis of the output end of the rotating mechanism 7, reducing the installation process, facilitating the installation of the limit pin 62b and the rotating mechanism 7, reducing the power consumption during the transmission of the rotating mechanism 7, improving the transmission efficiency between the rotating mechanism 7 and the second sliding part 32, and realizing the variable-center rotation of the display terminal. The fixed shaft 5 and the output shaft of the rotating mechanism 7 are coaxially arranged, which is beneficial to the overall structure layout of the actuator 100, making the installation of each component of the actuator 100 compact and reducing the space occupied by the actuator 100.

[0129] The lever 65 is fixedly connected to the fixed shaft 5, and the limit pin 62b is connected to the lever 65. One end of the lever 65 is fixed to the fixed shaft 5, and the other end of the lever 65 is installed with the limit pin 62b, wherein the fixed shaft 5 is arranged in parallel with the limit pin 62b, and the lever 65 is arranged perpendicular to the fixed shaft 5 and the limit pin 62b. Therefore, the axis of the limit pin 62b is parallel and spaced apart from the axis of the rotating mechanism 7, so that the geometric center of the first sliding part 31 is spaced apart from the rotation center of the second sliding part 32, which is convenient for the installation and fixation of other components of the actuator 100, and for the relative sliding of the first sliding part 31 and the second sliding part 32, thereby realizing the non-fixed center rotation of the display terminal 1, which is beneficial to improving the practicality of the actuator 100.

[0130] like Figures 9 - 10 As shown, the actuator 100 also includes an axial limit member 54, and the fixed shaft 5 includes a smooth rod segment 51, a circumferential limit segment 52 and an axial limit segment 53 connected in sequence, that is, one end of the circumferential limit segment 52 is connected to the smooth rod segment 51, and the other end of the circumferential limit segment 52 is connected to the axial limit segment 53, and the smooth rod segment 51 is fixedly assembled relative to the vehicle body. For example, a flange 55 is axially provided at the end of the smooth rod segment 51 away from the circumferential limit segment 52, and the flange 55 is provided with a plurality of threaded holes. The flange 55 can be connected to the vehicle body by threaded fasteners, or the flange 55 is connected to other components and fixed to the vehicle body together, so as to facilitate fixing the fixed shaft 5 to the vehicle body as a whole, and then fixing the limit pin 62b to the vehicle body through the fixed shaft 5, so that the installation of the actuator 100 is more stable.

[0131] like Figure 9 As shown, the shift rod 65 is sleeved on the circumferential limit section 52, and the circumferential limit section 52 can limit the shift rod 65 circumferentially, that is, the shift rod 65 and the fixed shaft 5 have no relative rotation, and one side of the shift rod 65 presses against the end face of the light rod section 51, the axial limit member 54 is connected to the axial limit section 53, and the axial limit member 54 presses against the other side of the shift rod 65, so that the two side surfaces of the shift rod 65 press against the light rod section 51 and the axial limit member 54 respectively, wherein the axial limit member 54 cooperates with the axial limit section 53, thereby stably fixing the shift rod 65 to the circumferential limit section 52, so that the shift rod 65 and the fixed shaft 5 are relatively fixed in the axial and circumferential directions, so as to facilitate the relative sliding of the first sliding part 31 and the second sliding part 32 through the shift rod 65, thereby ensuring the structural stability of the actuator 100.

[0132] Among them, Figure 10 As shown, the circumferential limit section 52 has a polygonal cross section, that is, the outer peripheral wall of the circumferential limit section 52 can be a polygonal column or a polygonal pyramid, such as Figure 12As shown, the lever 65 includes a connecting plate 66 and an extension plate 67. The connecting plate 66 and the extension plate 67 can be integrally formed, which is convenient for processing and assembly. The connecting plate 66 is connected to the fixed shaft 5, the extension plate 67 is connected to the connecting plate 66, and the limit pin 62b is connected to the end of the extension plate 67 facing away from the connecting plate 66, that is, the limit pin 62b is arranged on the side of the extension plate 67 facing away from the fixed shaft 5 to relatively fix the limit pin 62b and the fixed shaft 5.

[0133] As Figures 13 - 15 shown, when the display terminal 1 is in the initial position, the length direction of the lever 65 is parallel to the length direction of the guide plate 63b. When the display terminal 1 is in the intermediate position between the initial position and the target position, the included angle between the length direction of the lever 65 and the length direction of the guide plate 63b is 45°. When the display terminal 1 is in the target position, the length direction of the lever 65 is perpendicular to the length direction of the guide plate 63b, which is convenient for realizing the switching between the landscape and portrait modes of the display terminal 1.

[0134] The connecting plate 66 has a mounting hole 61. The mounting hole 61 penetrates axially and has a polygonal cross-section. The mounting hole 61 is sleeved on the circumferential limiting section 52. The mounting hole 61 is adapted to cooperate with the circumferential limiting section 52 to relatively fix the lever 65 and the fixed shaft 5 circumferentially. It should be noted that, as Figure 10 shown, the diameters of the smooth rod section 51, the circumferential limiting section 52, and the axial limiting section 53 decrease in sequence, that is, the diameter of the circumferential limiting section 52 is smaller than that of the smooth rod section 51, the diameter of the axial limiting section 53 is smaller than that of the circumferential limiting section 52, and the diameter of the mounting hole 61 is larger than that of the axial limiting section 53 and smaller than that of the smooth rod section 51. In this way, the lever 65 is inserted through the axial limiting section 53 and then installed on the circumferential limiting section 52, and the axial limiting member 54 is inserted from the end of the axial limiting section 53 facing away from the circumferential limiting section 52, and then the lever 65 is fixed between the axial limiting section 53 and the smooth rod section 51 to realize the fixation of the lever 65, which is convenient for installation and disassembly.

[0135] As Figure 10 shown, the axial limiting section 53 is an external thread section, and the axial limiting member 54 includes a nut. Thus, after the lever 65 is inserted through the axial limiting section 53, the nut is screwed and inserted from the end of the axial limiting section 53 facing away from the circumferential limiting section 52. The nut can axially fix the lever 65 and the fixed shaft 5, prevent the lever 65 from disengaging from the circumferential limiting section 52, avoid the relative rotation of the lever 65 and the fixed shaft 5 from affecting the meshing effect between the lever 65 and the guide plate 63b, and further ensure the stability and safety of the actuator 100, which is convenient for realizing the relative sliding between the display terminal 1 and the first sliding part 31.

[0136] The rotating mechanism 7 has a first avoidance hole that penetrates axially. The fixed shaft 5 penetrates through the first avoidance hole. Thus, the rotating mechanism 7 is installed on the fixed shaft 5 and further installed on the vehicle body, making the connection between the rotating mechanism 7 and the fixed shaft 5 more compact, saving installation space, facilitating the overall layout of the actuator 100, reducing the overall occupied space of the actuator 100, and improving the overall performance of the actuator 100.

[0137] A bearing (not shown in the figure) is provided between the fixed shaft 5 and the rotating mechanism 7, that is, the rotating mechanism 7 can slide relative to the fixed shaft 5 through the bearing. Among them, the inner wall of the first avoidance hole of the rotating mechanism 7 is fixedly connected to the outer ring of the bearing, and the outer peripheral wall of the fixed shaft 5 is fixedly connected to the inner ring of the bearing. For example, the outer peripheral wall of the smooth rod section 51 is fixedly connected to the inner ring of the bearing. Thus, when the inner ring and the outer ring of the bearing rotate relative to each other, the rotating mechanism 7 rotates relative to the fixed shaft 5. In this way, the rotating mechanism 7 is installed on the fixed shaft 5 through the bearing, facilitating the rotation of the rotating mechanism 7 to drive the display terminal 1 and at the same time facilitating the relative sliding between the first sliding portion 31 and the display terminal 1. The overall layout of the actuator 100 is reasonable, and the rotating mechanism 7, the fixed shaft 5 and other components are installed compactly, greatly improving the space utilization rate of the actuator 100, reducing the frictional loss of the relative rotation between the rotating mechanism 7 and the fixed shaft 5, and reducing the heat generated by friction.

[0138] In one embodiment, the fixed shaft 5 is a hollow shaft, that is, the fixed shaft 5 has a through hole extending circumferentially. The circuit of the display terminal 1 can pass through the through hole of the fixed shaft 5, facilitating wiring, being more suitable for the requirements of the overall vehicle mechanism with a compact space and vehicle weight limit, and at the same time can also give users a better driving experience.

[0139] As Figures 8 - 9 shown, the actuator 100 for adjusting the display terminal 1 according to the embodiment of the present invention further includes: a first bracket 2, a second bracket 4, and a third bracket 8.

[0140] The first bracket 2 is used to install the display terminal 1. As Figures 8 - 9 shown, the first bracket 2 is in a flat plate shape. The side of the first bracket 2 facing away from the first sliding portion 31 is attached to the display terminal 1. Thus, when the first bracket 2 is installed with the display terminal 1, there is a large contact surface, improving the stability of the installation of the display terminal 1. The first sliding portion 31 is connected to the first bracket 2, and the first sliding portion 31 and the first bracket 2 can be connected by a threaded fastener. For example, both the first sliding portion 31 and the first bracket 2 are provided with threaded holes, and a bolt can be passed through the threaded holes to connect the first sliding portion 31 and the first bracket 2. Moreover, the guide plate 63b is connected to the first bracket 2, and the guide plate 63b can be connected to the first bracket 2 by a threaded fastener. For example, the guide plate 63b is provided with a threaded hole for connecting to the first bracket 2, facilitating the relative fixation of the guide plate 63b and the first bracket 2.

[0141] In this way, the guide plate 63b and the first sliding part 31 are both stably fixed to the first bracket 2, and the display terminal 1 is relatively fixed to the first bracket 2, so that when the rotating mechanism 7 drives the first sliding part 31 and the second sliding part 32 to rotate, the first bracket 2 and the display terminal 1 rotate synchronously with the first sliding part 31, thereby ensuring that the various components of the actuator 100 are stably installed and reasonably fixed, and the overall structural layout is orderly, which is convenient for realizing the position adjustment of the display terminal 1 and completing the switching between the horizontal screen and the vertical screen of the display terminal 1, thereby improving practicality.

[0142] like Figures 8 - 9 As shown, the second bracket 4 is in the shape of a plate, and the second bracket 4 is connected to the second sliding part 32, for example, the second bracket 4 is connected to the second sliding part 32 by a threaded fastener, so that the second bracket 4 can move synchronously with the second sliding part 32, and the output end of the rotating mechanism 7 is connected to the second bracket 4, for example, the output end of the rotating mechanism 7 is connected to the second bracket 4 by a threaded fastener, thereby facilitating the driving force output by the rotating mechanism 7 to drive the second bracket 4 to rotate, thereby realizing the rotation adjustment of the first bracket 2 and the display terminal 1, and completing the switching of the horizontal screen and the vertical screen of the display terminal 1.

[0143] Among them, Figures 8 - 9 As shown, the second bracket 4 has a second avoidance hole 41, and the second avoidance hole 41 is axially penetrated. Figure 9 As shown, the fixed shaft 5 passes through the first avoidance hole and the second avoidance hole 41 in sequence, and after the fixed shaft 5 passes through the first avoidance hole and the second avoidance hole 41, the end of the fixed shaft 5 close to the display terminal 1 is fixedly connected to the lever 65, so that it is convenient to install or disassemble the actuator 100, so that the rotating bracket, the second bracket 4 and the fixed shaft 5 are installed more compactly, which greatly saves the installation space of the actuator 100, reduces the overall occupied space of the actuator 100, improves the practicality of the actuator 100, and facilitates the installation and layout of the actuator 100.

[0144] The third bracket 8 is a fixed bracket of the actuator 100. The rotating mechanism 7 is mounted on the third bracket 8. The third bracket 8 is used to be fixedly connected to the vehicle body. The first bracket 2, the second bracket 4 and the display terminal 1 of the actuator 100 are all fixed to the vehicle body through the third bracket 8. Figures 8 - 9 As shown, the third bracket 8 is in the shape of a plate, and the fixed shaft 5 is installed on the third bracket 8, wherein the flange 55 of the bare rod section 51 is closely connected to the third bracket 8, so that the driving action of the rotating mechanism 7 on the display terminal 1 is stably supported, ensuring that the rotating mechanism 7 can accurately and effectively drive the display terminal 1 to rotate, thereby improving the rationality of the overall structure of the actuator 100.

[0145] In some embodiments, the extending direction of the guide groove 64 is perpendicular to the sliding direction of the sliding mechanism. The extending direction of the guide groove 64 is perpendicular to the first sliding part 31 and the second sliding part 32. When the first sliding part 31 and the second sliding part 32 slide relative to each other, the guide plate 63b moves synchronously and in the same direction as the first sliding part 31, which facilitates the installation of the guide plate 63b and the sliding mechanism 3. The movement of the guide plate 63b does not interfere with the movement of the first sliding part 31, making it easy to realize the relative sliding between the display terminal 1 and the second sliding part 32, and the movement structure of the actuator 100 is more reasonable. Of course, the extending direction of the guide groove 64 can also be parallel to the sliding direction of the sliding mechanism or set at other angles.

[0146] As Figures 8 - 9 shown, there are multiple sliding mechanisms 3 arranged in parallel at intervals. The multiple sliding mechanisms 3 can stably support the relative sliding of the first bracket 2 and the second bracket 4, ensuring the stability of the relative sliding of the first bracket 2 and the second bracket 4. And sliding mechanisms 3 are provided on both sides of the guide plate 63b, that is, multiple sliding mechanisms 3 are respectively arranged on both sides of the guide plate 63b. For example, there are two sliding mechanisms 3, and the two sliding mechanisms 3 are respectively distributed on both sides of the guide plate 63b. In this way, it is not only convenient for the overall layout of the sliding mechanism 3 and the guide plate 63b, but also can ensure that the first bracket 2 and the second bracket 4 can stably slide relative to each other, making the structural design of the actuator 100 more reasonable and reliable.

[0147] The actuator 100 of any of the above embodiments includes a rotating mechanism 7. The rotating mechanism 7 is used to drive the display terminal 1 to rotate, so as to facilitate the rotating mechanism 7 to drive the display terminal 1 to switch between a landscape screen and a portrait screen. The rotating mechanism 7 is adapted to be installed on the vehicle body, and the output end of the rotating mechanism 7 is connected to the second bracket 4. The output end of the rotating mechanism 7 can drive the second bracket 4 to rotate, that is, the driving force output by the output shaft can drive the second bracket 4 to rotate. The second bracket 4 drives the first bracket 2 and the display terminal 1 to rotate, realizing the rotational adjustment of the display terminal 1.

[0148] As Figure 4 shown, the rotating mechanism 7 includes a rotating disk 71, a clutch unit 72, a driving unit 75, and a mounting shaft 78.

[0149] As Figure 4 shown, the rotating disk 71 is connected to the second bracket 4. The first engaging part 73 of the clutch unit 72 is connected to the rotating disk 71. The second engaging part 74 of the clutch unit 72 is always locked with the first engaging part 73. The first engaging part 73 and the second engaging part 74 are engaged and have multiple engaging positions. The rotating disk 71 is configured to be manually rotatable to drive the first engaging part 73 to rotate relative to the second engaging part 74 and switch between multiple engaging positions. The output end of the driving unit 75 is connected to the second engaging part 74.

[0150] AsFigure 4 As shown, the rotating disk 71 is power-coupled to the first engaging portion 73. The rotating disk 71 and the first engaging portion 73 are connected by splines. For example, an internal spline is provided on the end face of the rotating disk 71 facing away from the display terminal 1, and an external spline is provided on the end face of the first engaging portion 73 facing away from the second engaging portion.

[0151] Of course, the rotating disk 71 and the first engaging portion 73 can also be integrally formed, which can reduce the number of components to be assembled and reduce the assembly process.

[0152] As Figure 4 shown, the rotating disk 71 can be disk-shaped, and a circular through-hole is provided in the middle of the rotating disk 71, that is, the rotating disk 71 is annular. The mounting shaft 78 extends axially from the inner circumference of the rotating disk 71. The rotating disk 71 is connected to the mounting shaft 78, and the mounting shaft 78 and the rotating disk 71 can be formed as one body. Of course, the mounting shaft 78 and the rotating disk 71 can be split and connected by a clamping structure.

[0153] As Figure 4 shown, the mounting shaft 78 penetrates through the clutch unit 72 and the driving unit 75. The mounting shaft 78 is used to string all the components into a whole. The mounting shaft 78 does not transmit power. When the rotating disk 71 rotates, the mounting shaft 78 can remain stationary. The mounting shaft 78 can be a hollow shaft, and a fixed shaft can penetrate through the mounting shaft to mount the rotating mechanism 7 on the fixed shaft to reduce weight and facilitate wire routing. The clutch unit 72 is located outside the housing of the driving unit 75.

[0154] As Figure 4 shown, when the second engaging portion 74 engages with the first engaging portion 73, the clutch unit 72 can transmit torque. The second engaging portion 74 and the first engaging portion 73 have multiple engaging positions. For example, multiple engaging positions are formed on the end faces of the first engaging portion 73 and the second engaging portion 74 that are oppositely arranged. The output end of the driving unit 75 is power-coupled to the second engaging portion 74, and the clutch unit 72 is located outside the housing of the driving unit 75.

[0155] As Figure 4 shown, or the clutch unit 72 includes a first engaging portion 73 and a second engaging portion 74 with opposite end faces, as Figure 4As shown, one of the two end faces of the first engaging portion 73 and the second engaging portion 74 facing each other has a plurality of locking grooves, and the other has at least one locking projection. The actuating mechanism 100 may further include a component for providing an axial pre-tightening force. Each locking projection is adapted to engage with at least two locking grooves under the action of the axial pre-tightening force so that the second engaging portion 74 and the first engaging portion 73 are adapted to engage at least at two circumferentially distributed engaging positions. When changing the engaging position, the second engaging portion 74 and the driving unit 75 remain relatively stationary axially, and the first engaging portion 73 moves axially in a direction away from the second engaging portion 74. The first engaging portion 73 is connected to the rotating disk, and the output end of the driving unit 75 is connected to the second engaging portion 74.

[0156] When changing the engaging position, the second engaging portion 74 and the driving unit 75 remain relatively stationary axially, and the first engaging portion 73 moves axially in a direction away from the second engaging portion 74. Thereby, the internal components of the driving unit 75 can be prevented from shaking, so that the driving and transmission of the driving unit 75 are more stable.

[0157] The driving unit 75 can be electrically driven, hydraulically driven, pneumatically driven, etc.

[0158] The clutch unit 72 can be located outside the housing of the driving unit 75. In this way, when assembling the clutch unit 72, it is not easy to interfere with the various components of the driving unit 75, and there is no need to separately design the installation space for the clutch unit 72 inside the housing of the driving unit 75, which can simplify the design. Further, since the first engaging portion 73 and the second engaging portion 74 of the clutch unit 72 rotate relative to each other in the manual mode, if a part of the clutch unit 72 is arranged inside the housing of the driving unit 75, problems such as jamming may occur during the operation of the actuating mechanism 100.

[0159] The clutch unit 72 is at least partially located within the rotating disk. For example, at least a part of the first engaging portion 73 or the second engaging portion 74 as described in the above embodiment is located within the rotating disk 71, which can significantly reduce the overall axial length of the actuating mechanism 100, make the layout more compact and reasonable, and the connection more tight.

[0160] The first engaging portion 73 and the second engaging portion 74 are normally locked to each other, and the rotating disk is configured to be manually rotatable to drive the first engaging portion 73 to rotate relative to the second engaging portion 74 and switch between a plurality of engaging positions.

[0161] When the second joint portion 74 engages with the first joint portion 73 during the operation of the drive unit 75, it can be understood that, in the normal state, the first joint portion 73 and the second joint portion 74 are engaged with each other under the action of an axial preloading force and can transmit torque. The driving force is transmitted along the drive unit 75 - the second joint portion 74 - the first joint portion 73 - the rotating disk 71 - the second bracket 4 - the display terminal 1, so as to rotate the display terminal 1 and realize the rotation of the display terminal 1 or the switching between the vertical and horizontal screens.

[0162] The first joint portion 73 and the second joint portion 74 form a circumferential static friction force under the action of an axial preloading force, and this circumferential static friction force forms an opening force for the relative rotation of the first joint portion 73 and the second joint portion 74. When the torque received by the first joint portion 73 is greater than this opening force, the first joint portion 73 and the second joint portion 74 rotate relative to each other to change the joint position; when the torque received by the first joint portion 73 is less than this opening force, the first joint portion 73 and the second joint portion 74 remain engaged with each other to transmit torque.

[0163] Specifically, during the operation of the actuator 100, when the drive unit 75 is not working and the torque received by the first joint portion 73 is greater than the above-mentioned opening force, the second joint portion 74 rotates relative to the first joint portion 73 to change the joint position.

[0164] For example, manually apply a torque to the display terminal 1 to make it rotate. This torque is transmitted to the first joint portion 73 through the rotating disk. Since the drive unit 75 is locked when it is not working and the drive unit 75 is fixedly connected to the second joint portion 74, when the above-mentioned torque is not greater than the above-mentioned opening force, the first joint portion 73 and the second joint portion 74 remain engaged and the display terminal 1 does not rotate; when the above-mentioned torque is greater than the above-mentioned opening force, the first joint portion 73 and the second joint portion 74 rotate relative to each other and rotate from the previous joint position to another joint position. When the first joint portion 73 rotates from the first joint position to the second joint position relative to the second joint portion 74, the manual rotation of the display terminal 1 can be realized.

[0165] According to the actuator 100 for adjusting the display terminal 1 in the embodiment of the present invention, the manual rotation of the display terminal 1 and the automatic rotation of the display terminal 1 are coupled into a whole through the clutch unit 72, and the two screen switching methods do not interfere with each other.

[0166] In some embodiments, the drive unit 75 includes: a power source 75a and a speed reducer 75b. The output shaft of the power source 75a is connected to the input end of the speed reducer 75b, the output end of the speed reducer 75b is connected to the display terminal 1, or the output end of the speed reducer 75b is connected to the second joint portion 74 and drives the display terminal 1 through the second joint portion 74 and the first joint portion 73.

[0167] The power source 75a can be a motor, an oil pump, an air pump, etc. For example, the power source 75a is a driving motor, and the speed reducer 75b can be a gear speed reducer, a belt drive reduction, or the speed reducer 75b can also be a worm gear transmission mechanism, etc. The speed reducer 75b can be a single-stage reduction mechanism or a multi-stage reduction mechanism.

[0168] The driving unit 75 for driving the movement of the display terminal includes: a power source 75a and a speed reducer 75b. The speed reducer 75b includes a driving worm and a driven spur gear. The driving worm is connected to the output shaft of the power source 75a, and the driven spur gear meshes with the driving worm.

[0169] Adopting a worm and spur gear reduction mechanism, this mechanism is compact, small in volume, light in weight, and has stable transmission and low noise. The entire reduction mechanism has a flexible layout, is convenient for wiring, and is more suitable for the requirements of the compact space of the vehicle body and the vehicle weight limit. At the same time, it can also give users a better driving experience.

[0170] The output shaft of the power source 75a and the driving worm of the speed reducer 75b can be detachably connected through a coupling. The driving worm is pivotally installed on the housing of the driving unit 75, and the driving worm is axially positioned and mated with the housing of the driving unit 75. In other words, the driving worm cannot move relative to the housing of the driving unit 75 axially (ignoring the assembly clearance).

[0171] It can be understood that the power source 75a outputs the rotational speed to the driving worm through the coupling. When the power source 75a is damaged, only the power source 75a needs to be disassembled through the coupling. Since the driving worm is axially positioned on the housing of the driving unit 75, when disassembling the power source 75a, it does not affect the meshing between the driving worm and the gear in the speed reducer 75b, and the power source 75a and the speed reducer 75b can be separately installed and fixed, which can weaken the influence of the vibration of the power source 75a on the components in the speed reducer 75b and prevent the driving worm from swinging.

[0172] According to the driving unit 75 for driving the in-vehicle display terminal movement in the embodiment of the present invention, by setting the coupling, the meshing stability of the components in the speed reducer 75b can be improved, the service life of the driving unit 75 can be increased, and the power source 75a can be separately repaired without affecting the meshing condition of the worm and gear.

[0173] The housing of the driving unit 75 is provided with an axial limiting and supporting structure. The driving worm is supported by the axial limiting and supporting structure, and the shoulder of the driving worm is oppositely arranged with the end face of the axial limiting and supporting structure to achieve axial positioning.

[0174] The housing of the driving unit 75 includes: a housing body 77a, a front cover of the housing, and a rear cover 77c of the housing.

[0175] The housing body 77a defines a first cavity and a second cavity. The first cavity and the second cavity are separated by a partition plate. The power source 75a is installed in the first cavity, and the driving worm is installed in the second cavity. The partition plate is provided with an avoidance hole, and the driving worm extends into the first cavity through the avoidance hole and is detachably connected to the output shaft of the power source 75a. The partition plate may be provided with an axial limit support structure at the avoidance hole. The partition plate is used to distinguish two installation cavities and can axially limit the driving worm to prevent the driving worm from shaking when the power source 75a is disassembled. One end of the first cavity facing away from the second cavity is open. The rear cover 77c of the housing is connected to the housing body 77a to close the open end of the first cavity. The front cover of the housing is connected to the housing body 77a to close the open end of the second cavity. The coupler is installed in the first cavity. The front cover of the housing is provided with a bushing. The driving worm is supported in the bushing, and the shaft shoulder of the driving worm is arranged opposite to the end face of the bushing, which is convenient for installation and disassembly.

[0176] The included angle between the axis of the driving worm and the axis of the driven spur gear is an acute angle. The included angle between the axis of the driving worm and the axis of the driven spur gear is an acute angle α, satisfying: 82° ≤ α ≤ 88°. Further, 84° ≤ α ≤ 86°, for example, α = 85°. The size of α is determined according to the helix angle of the driving worm.

[0177] That is to say, the driving worm and the driven spur gear are not vertically arranged, which can ensure a good meshing state between the driving worm and the driven spur gear and higher transmission efficiency. The spur gear is convenient to process. The worm and worm gear transmission in the related technology is improved to a worm and spur gear transmission, thus avoiding the problem of poor machining performance of the worm wheel.

[0178] In some embodiments, the reducer 75b is a single-stage transmission mechanism, and the reducer 75b includes: a single-stage driving worm and a single-stage driven spur gear. The single-stage driving worm is connected to the output shaft of the power source 75a. The output shaft of the power source 75a and the single-stage driving worm may be fixedly connected, or the output shaft of the power source 75a and the single-stage driving worm are detachably connected through a coupler. The single-stage driving worm meshes with the single-stage driven spur gear, and the included angle between the axis of the single-stage driving worm and the axis of the single-stage driven spur gear is an acute angle. Project the axis L1 of the single-stage driving worm and the axis L2 of the single-stage driven spur gear onto a projection plane parallel to these two axes, and the included angle between the axis of the single-stage driving worm and the axis of the single-stage driven spur gear is α, satisfying: 82° ≤ α ≤ 88°. Further, 84° ≤ α ≤ 86°, for example, α = 85°. The size of α is determined according to the helix angle of the single-stage driving worm. That is to say, the single-stage driving worm and the single-stage driven spur gear are not vertically arranged, which can ensure a good meshing state between the single-stage driving worm and the single-stage driven spur gear and higher transmission efficiency. The spur gear is convenient to process. The worm and worm gear transmission in the related technology is improved to a worm and spur gear transmission, thus avoiding the problem of poor machining performance of the worm wheel.

[0179] In some other embodiments, as Figure 4 shown, the speed reducer 75b is a two-stage transmission mechanism, and the speed reducer 75b includes: a first-stage driving worm 75c, a first-stage driven spur gear 75d, a second-stage driving worm 75e, and a second-stage driven spur gear 75f.

[0180] Among them, as Figure 4 shown, the output shaft of the power source 75a is connected to the first-stage driving worm 75c. The first-stage driving worm 75c can be integrated outside the output shaft of the power source 75a. The output shaft of the power source 75a and the first-stage driving worm can be fixedly connected, or the output shaft of the power source 75a and the first-stage driving worm can be detachably connected through a coupling.

[0181] The first-stage driving worm 75c meshes with the first-stage driven spur gear 75d. The included angle between the axis of the first-stage driving worm 75c and the axis of the first-stage driven spur gear 75d is an acute angle. Project the axis L1 of the first-stage driving worm 75c and the axis L2 of the first-stage driven spur gear 75d onto a projection plane parallel to these two axes to obtain the included angle α between the axis of the first-stage driving worm 75c and the axis of the first-stage driven spur gear 75d, which satisfies: 82° ≤ α ≤ 88°. Further, 84° ≤ α ≤ 86°. For example, α = 85°. The size of α is determined according to the helix angle of the first-stage driving worm 75c. That is to say, the first-stage driving worm 75c and the first-stage driven spur gear 75d are not vertically arranged, which can ensure a good meshing state between the first-stage driving worm 75c and the first-stage driven spur gear 75d and higher transmission efficiency. The spur gear is convenient to process. The worm and worm gear transmission in the related technology is improved to a worm and spur gear transmission, thus avoiding the problem of poor machining performance of the worm wheel.

[0182] The second-stage driving worm 75e is coaxially arranged with the first-stage driven spur gear 75d. The second-stage driving worm 75e and the first-stage driven spur gear 75d are arranged at an axial interval. The second-stage driving worm 75e and the first-stage driven spur gear 75d can be integrally processed, or the first-stage driven spur gear 75d can be connected to the second-stage driving worm 75e through a spline.

[0183] The secondary driven spur gear 75f meshes with the secondary driving worm 75e, and the secondary driven spur gear 75f is used to output the driving force of the driving unit 75. The angle between the axis of the secondary driving worm 75e and the axis of the secondary driven spur gear 75f is an acute angle. Project the axis L3 of the secondary driving worm 75e and the axis L4 of the secondary driven spur gear 75f onto a projection plane parallel to these two axes to obtain the angle β between the axis of the secondary driving worm 75e and the axis of the secondary driven spur gear 75f, satisfying: 82° ≤ β ≤ 88°, and further, 84° ≤ β ≤ 86°. For example, β = 85°, and the size of β is determined according to the helix angle of the secondary driving worm 75e. That is to say, the secondary driving worm 75e and the secondary driven spur gear 75f are not vertically arranged, which can ensure a good meshing state between the secondary driving worm 75e and the secondary driven spur gear 75f and higher transmission efficiency. The spur gear is convenient to process, and the worm and worm gear transmission in the related technology is improved to worm and spur gear transmission, thus avoiding the problem of poor machining performance of the worm gear.

[0184] The axis of the primary driving worm 75c, the axis of the secondary driven spur gear 75f, and the axis of the clutch unit are parallel. The axis of the output shaft of the power source 75a is parallel to and spaced apart from the axis of the secondary driven spur gear 75f. Thus, it can be realized that the arrangement direction of the power source 75a is parallel to the output direction of the driving unit 75, which is convenient for assembly design.

[0185] When the power source 75a is not working, by using the self-locking function of the worm (the self-locking can be triggered when the helix angle of the worm is less than the friction angle), the clutch function of the overall scheme can be realized. That is, when manually operating, the reducer 75b is self-locked, so that the second engaging portion 74 is fixed, and thus the first engaging portion 73 can rotate relatively.

[0186] The worm and spur gear reduction mechanism is adopted. This mechanism is compact, small in volume, light in weight, and has stable transmission and low noise. The layout of the entire reduction mechanism is flexible, convenient for wiring, more suitable for the requirements of the compact space of the vehicle body mechanism and the vehicle weight limit, and can also give users a better driving experience.

[0187] As Figure 4 shown, the primary driven spur gear 75d transmits the high-speed rotation of the primary driving worm 75c to the secondary driving worm 75e. In order to reduce the vibration during the transmission process, the primary driven spur gear 75d can be a plastic part, and the primary driving worm 75c, the secondary driving worm 75e, and the secondary driven spur gear 75f are metal parts.

[0188] The secondary driven spur gear 75f is connected to the second engaging portion 74 to achieve power output. For example, the secondary driven spur gear 75f and the second engaging portion 74 are formed as one body. According to the functional requirements of the secondary driven spur gear 75f and the second engaging portion 74, they can be made of different materials. The secondary driven spur gear 75f is made of wear-resistant material, and the second engaging portion 74 is made of self-lubricating material, such as polyoxymethylene, molybdenum disulfide, boron nitride, etc.

[0189] The drive unit 75 may further include: an output interface connected to the secondary driven spur gear 75f. The output interface is used to output driving force, and the output interface can be the second engaging portion 74 of the clutch unit.

[0190] Both the output interface and the secondary driven spur gear 75f are hollow rings.

[0191] The first engaging portion 73, the second engaging portion 74, and the secondary driven spur gear 75f adopt a hollow shape to facilitate wire routing and weight reduction. Moreover, the torque input end and the output end are not on the same axis. With the hollow shaft and the transmission system, the input and output shafts can be processed into parallel shaft directions, which is beneficial to the spatial planning of the structure and provides a greater design margin.

[0192] The primary driving worm 75c is fixedly connected to the motor shaft, with one end extending from the motor and the other end limited by the housing structure. The primary driven spur gear 75d and the secondary driving worm 75e are fixed on the same shaft. Due to space limitations, bearings are not used at both ends, but shoulder bushings are used, and there is lubrication inside. The secondary driven spur gear 75f is also limited by the housing structure, with one end integrated with the output structure and the other end supported by a face bearing. Both the bushing and the face bearing reduce the frictional loss during rotation and reduce heat generated by friction.

[0193] The secondary driven spur gear 75f can be a hollow gear. On the one hand, it can reduce the weight of the entire drive unit 75, and on the other hand, it is convenient for assembly.

[0194] The housing of the drive unit 75 includes: a housing body 77a, a rear housing cover 77c, an upper housing cover 77b, and a front housing cover.

[0195] The power source 75a, the primary driving worm 75c, the primary driven spur gear, and the secondary driving worm 75e are all installed in the housing body 77a. The secondary driven spur gear 75f is installed in the upper housing cover 77b. The primary driven spur gear and the secondary driving worm 75e are fixed on the same shaft. Due to space limitations, bearings are not used at both ends, but shoulder bushings are used, and there is lubrication inside.

[0196] The housing body 77a is a plastic part, and the upper housing cover 77b is a metal part. It can be understood that the housing body 77a mainly bears high-speed components, and setting a plastic part is beneficial for shock absorption; the upper housing cover 77b mainly bears low-speed components and is processed by an integral molding method.

[0197] In some other alternative embodiments, the housing body 77a and the upper housing cover 77b can be an integral part.

[0198] The rear housing cover 77c is connected to the housing body 77a to enclose the rear end of the housing body 77a. The upper housing cover 77b is connected to the housing body 77a, and the front housing cover is connected to the housing body 77a to enclose the front end of the housing body 77a. The rear housing cover 77c, the upper housing cover 77b, and the front housing cover can be connected to the housing body 77a through a snap structure and threaded fasteners.

[0199] In the entire system of the drive unit 75, the housing will be subjected to impact loads. When the second engagement portion 74 rotates, it is subjected to axial positive pressure and circumferential torque, which will be transmitted to the housing. Therefore, in order to ensure the stability of the drive unit 75, in addition to the connection of screws and snap fasteners between the components, the drive unit 75 is also fastened to the base in the actuator 100 with screws to increase the strength of the drive unit 75 and improve its service life.

[0200] The housing of the drive unit 75 has an axial limiting portion. The end face of the secondary driven spur gear 75f facing away from the display terminal 1 presses against the axial limiting portion, and the end face of the secondary driven spur gear 75f facing away from the second engagement portion 74 presses against the axial limiting portion. Specifically, the upper housing cover 77b can have an axial limiting portion for limiting the end face of the secondary driven spur gear 75f. In this way, one end face of the secondary driven spur gear 75f is connected to the second engagement portion 74, and the other end face of the secondary driven spur gear 75f presses against the upper housing cover 77b to ensure the axial positioning of the secondary driven spur gear 75f and prevent the secondary driven spur gear 75f from engaging with the secondary driving worm 75e.

[0201] The secondary driven spur gear 75f presses against the axial limiting portion through a gear end face bearing. The gear end face bearing can be a thrust bearing, which can reduce the friction between the secondary driven spur gear 75f and the housing of the drive unit 75 and reduce torque loss. In another structure, an annular groove can be provided on the upper housing cover 77b for assembling the gear end face bearing.

[0202] An annular groove may be provided on the end face of the secondary driven spur gear 75f facing away from the second joint portion 74. A gear end face bearing is provided in the annular groove, and the gear end face bearing presses against the bottom wall of the annular groove. At least a part of the axial limiting portion extends into the annular groove. Further, the axial limiting portion may be provided with a deep groove shape. One end face of the axial limiting portion presses against the end face bearing of the elastic body 76, and the other end face of the axial limiting portion presses against the gear end face bearing. The gear end face bearing is also in the annular groove of the secondary driven spur gear 75f. At least a part of the elastic body 76 may be located in the annular groove of the secondary driven spur gear 75f. This can shorten the axial length of the entire mechanism, save space, and make the applicability of the entire mechanism more extensive. Moreover, from the perspective of structural mechanics, the stiffness of the system is also improved, strengthening its bending and torsion resistance capabilities.

[0203] The upper cover 77b of the housing has a sleeve, and the secondary driven spur gear 75f is sleeved outside the sleeve. The axial limiting portion is located on the outer peripheral surface of the sleeve.

[0204] The housing of the drive unit 75 has a radial retaining mechanism, and the second joint portion 74 is rotatably provided on the radial retaining mechanism for radial positioning. The radial retaining mechanism is used to limit the radial offset of at least part of the rotating components, preventing the actuator 100 from having a radial offset during operation. In this way, the actuator 100 can still maintain stable operation after long-term operation.

[0205] In some alternative embodiments, the housing of the drive unit 75 is fixedly installed on the vehicle body. The housing of the drive unit 75 has two outer rings and inner rings that are sleeved loosely. The radial retaining mechanism includes the outer ring and the inner ring. The outer ring is sleeved on the inner and outer rings. The outer ring and the inner ring define an annular cavity. At least part of the second joint portion 74 is provided in the annular cavity. At least part of the second joint portion 74 is sleeved outside the inner ring. The inner ring is used to prevent the second joint portion 74 from offsetting radially inward. The outer ring is sleeved on at least part of the second joint portion 74. The outer ring is used to prevent the second joint portion 74 from offsetting radially outward.

[0206] In some alternative embodiments, the housing of the drive unit 75 includes: a housing body 77a, an upper cover 77b of the housing, and a front cover of the housing. The upper cover 77b of the housing is connected to the housing body 77a, and the upper cover 77b of the housing has an annular sleeve. The front cover of the housing is connected to the front end of the housing body 77a, and the front cover of the housing has an annular limiting ring. The limiting ring is sleeved loosely outside the sleeve to define an annular cavity. At least part of the second joint portion 74 is provided in the annular cavity. At least part of the second joint portion 74 is sleeved outside the sleeve. The sleeve is used to prevent the second joint portion 74 from offsetting radially inward. The limiting ring is sleeved on at least part of the second joint portion 74. The limiting ring is used to prevent the second joint portion 74 from offsetting radially outward.

[0207] As Figure 4As shown, the output part of the driving unit 75 includes an annular output gear, which can be the secondary driven spur gear 75f described in the above embodiments. The output gear is connected to the second engaging part 74 and is sleeved outside the sleeve. The second engaging part 74 includes an engaging disc for locking with the first engaging part 73 and a connecting sleeve connected to one end of the engaging disc facing away from the first engaging part 73. The connecting sleeve is connected to the output gear, and a limiting ring is sleeved outside the connecting sleeve. In this way, the inner and outer sides in the radial direction of the output gear are respectively limited by the sleeve and the limiting ring. During the working process, the output end of the driving unit 75 is not easily affected by external vibrations, preventing gear teeth from being damaged.

[0208] The radial holding mechanism may further include a radial limiting bearing (not shown in the figure). A radial limiting bearing is provided between the limiting ring and at least a part of the second engaging part 74. For example, a radial limiting bearing may be provided between the limiting ring and the connecting sleeve. In this way, the inner ring of the radial limiting bearing presses against the connecting sleeve, and the outer ring of the radial limiting bearing presses against the limiting ring, making the radial limitation of the radial holding mechanism more stable.

[0209] Thus, the power output by the power source 75a is transmitted to the rotating disc 71 through the speed reducer 75b. Then, the rotating disc 71 drives the first bracket 2, the second bracket 4, and the display terminal 1 to rotate simultaneously, realizing the switching between the landscape and portrait screens of the display terminal 1. The adjustment process is simple and convenient for the occupant to use.

[0210] In some embodiments, a current-limiting circuit board (not shown in the figure) is embedded in the driving motor. When a current exceeding the set threshold is detected, the driving motor is powered off. For example, when there is an object clamped between the first bracket 2 and the second bracket 4 during the relative movement of the first bracket 2 and the second bracket 4, or when a part of the human body is located between the first bracket 2 and the second bracket 4, the driving motor cannot effectively drive the display terminal 1 to move, and the driving motor is powered off. Thus, it can prevent the actuator 100 from pinching the occupant or damaging other objects, avoid the actuator 100 being damaged due to forced rotation, and further improve the safety of the actuator 100, enhance the use performance of the whole vehicle, and achieve the safety anti-pinch and overload protection of the actuator 100.

[0211] In some embodiments, when the display terminal 1 reaches 90° after adjustment or the anti-pinch indication is activated due to external resistance on the display terminal 1, it is achieved by relying on the current increase exceeding the design threshold of the current-limiting small board, and the actuator 100 cuts off the power supply to the drive motor. After the motor power is cut off, the actuator 100 will determine whether the display terminal 1 is in an abnormal position based on the signal transmitted by the built-in gyroscope of the display terminal 1. If the signal transmitted by the gyroscope indicates that the display terminal 1 is in the landscape position or the portrait position, it means that the drive motor power-off is a power-off when in place. Otherwise, it is determined that the display terminal 1 is in an abnormal position, and it is determined that the drive motor power-off is an abnormal power-off due to being blocked, then a warning screen appears to remind the occupant to check for foreign objects. After the resistance disappears, it will be restarted and returned according to the occupant's selection. The abnormal position determination includes manual operations in the automatic operation state. The actual abnormal position feedback processing can be designed according to the occupant's requirements to define the software function, thereby realizing the in-place and abnormal position control of the display terminal 1 and improving the use performance of the whole vehicle.

[0212] As Figure 5 shown, the rotating disk 71 has a limiting post 711, and the housing is provided with a first limiting boss 77d and a second limiting boss 77e. The limiting post 711 abuts against the first limiting boss 77d and the second limiting boss 77e respectively when in the landscape and portrait positions. For example, when the display terminal 1 is in the landscape position, the limiting post 711 abuts against the first limiting boss 77d. When the rotating mechanism 7 drives the rotating disk 71 to rotate 90°, when the display terminal 1 is in the portrait position, the limiting post 711 of the rotating disk 71 contacts the limiting post collision point of the second limiting boss 77e of the housing of the rotating mechanism 7. At this time, the drive motor is blocked, the current increases, the actuator 100 detects the blocking signal, and the built-in gyroscope of the display terminal 1 transmits the in-place signal. The actuator 100 identifies the in-place and cuts off the power supply to the drive motor, and the power system transmission is interrupted, and the system is locked in place.

[0213] The present invention also proposes a display terminal assembly.

[0214] The display terminal assembly according to an embodiment of the present invention includes a display terminal and the actuator 100 in any of the above embodiments. The connection position of the drive mechanism to the display terminal 1 is located at a non-central position of the display terminal 1, and the axis of the output end of the rotating mechanism 7 is spaced apart from the geometric center of the display terminal 1. Thus, when the rotating mechanism 7 drives the display terminal 1 to rotate, the geometric center of the display terminal 1 gradually shifts, thereby realizing the variable-center rotation of the display terminal 1.

[0215] According to the display terminal assembly of the embodiment of the present invention, the lower edges of the display terminal 1 are flush at the initial position and the target position. In this way, when the display terminal 1 is in the landscape or portrait orientation, the lower part of the display terminal 1 does not interfere with the arrangement and installation of other components, reducing the space occupied by the position adjustment of the display terminal 1, facilitating the design of the overall structure inside the vehicle, and improving the rationality of the design of the actuator 100.

[0216] The present invention also provides a vehicle.

[0217] The vehicle according to the embodiment of the present invention includes a display terminal 1 and the display terminal assembly of the above embodiment. The display terminal 1 is connected to the first sliding part 31 of the actuator 100.
