DETAILED DESCRIPTION

[0032] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0033] In the present disclosure, unless otherwise stated, the directions or positional relationships indicated by the directional words such as "first direction" and "second direction" are based on the attached Figure 1 The directions of the drawings shown are defined only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, it cannot be understood as a limitation of the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.

[0034] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0035] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0036] refer to Figures 1 to 3As shown, the first aspect of the present disclosure provides a display screen adjustment device 1, including a fixing member 10, a first swinging member 20, a second swinging member 30 and a driving assembly 40, the first swinging member 20 is connected to the fixing member 10 and can swing around a first swing axis X, the second swinging member 30 is connected to the first swinging member 20 and can rotate around the second swing axis Y, the second swinging member 30 is used to be connected to the display screen, and the driving assembly 40 is used to drive the first swinging member 20 to swing around the first swing axis X and the second swing axis Y to swing around the second swing axis Y; the first swing axis X and the second swing axis Y intersect.

[0037] According to the above technical solution, since the second swinging member 30 is connected to the display screen, and the first swinging member 20 is connected to the fixing member 10 and can swing around the first swinging axis X, the second swinging member 30 is connected to the first swinging member 20 and can rotate around the second swinging axis Y, when the tilt angle of the display screen in the first direction needs to be adjusted, the first swinging member 20 can be driven by the driving assembly 40 to swing around the first swinging axis X, thereby driving the second swinging member 30 connected to the first swinging member 20 to swing around the first swinging axis X, and then driving the display screen to swing around the first swinging axis X; when the tilt angle of the display screen in another direction needs to be adjusted, the second swinging member 30 can be driven by the driving assembly 40 to swing around the second swinging axis Y, so that the display screen can swing around the first swinging axis X and the second swinging axis Y in a different direction from the first swinging axis X under the driving action of the driving assembly 40, thereby realizing the adjustment of the angle of the display screen in multiple directions, so that the display screen has a higher degree of freedom during the adjustment process, thereby matching the use needs of users of different heights, weights, and sitting postures.

[0038] Furthermore, the display screen adjustment device 1 provided in the present disclosure has a relatively simple structure, which makes it convenient for the user to adjust the angle of the display screen by controlling the driving component 40 and can reduce the processing cost.

[0039] The present disclosure does not limit the specific application scenarios of the above-mentioned display screen adjustment device 1. For example, the display screen adjustment device 1 can be used in places such as vehicles, factories, and office buildings. For the implementation of the display screen adjustment device 1 being applied in a vehicle, the above-mentioned fixing member 10 can be fixedly connected to the dashboard of the vehicle.

[0040] It should be noted that the present disclosure does not limit the specific range of the angle between the first swing axis X and the second swing axis Y, as long as the two are not collinear. For example, in an exemplary embodiment provided by the present disclosure, the angle between the first swing axis X and the second swing axis Y can be a right angle.

[0041] Specifically, for the implementation of setting the display screen adjustment device 1 in the vehicle cockpit, in order to facilitate the user's use of the display screen, the above-mentioned first swing axis X can extend in the horizontal direction, and the second swing axis Y can extend in the oblique upward direction. In this way, when adjusting the display screen, it is more in line with the user's usage habits.

[0042] In addition, the present disclosure does not limit the angle at which the display screen can swing around the first swing axis X and the angle at which the display screen can swing around the second swing axis Y.

[0043] In an exemplary embodiment provided by the present disclosure, optionally, two first hinge holes 11 arranged opposite to each other may be formed on the fixing member 10, and first connecting shafts 21 are formed on both sides of the first swinging member 20, and the first connecting shafts 21 are arranged corresponding to the first hinge holes 11 and are rotatably connected in the first hinge holes 11, and the central axis of the first connecting shaft 21 is colinear with the first swing axis X. In this way, the first connecting shafts 21 on both sides of the first swinging member 20 are rotatably connected in the first hinge holes 11, so that the first swinging member 20 can swing around the first connecting shaft 21 under the drive of the driving assembly 40, and the first connecting shaft 21 is colinear with the first swing axis X, so that the first swinging member 20 can swing around the first swing axis X.

[0044] Alternatively, in other embodiments provided in the present disclosure, hinge holes may be formed on both sides of the first swinging member 20, and a hinge shaft may be formed on the fixing member 10, and the hinge shaft may be inserted into the hinge holes to achieve a detachable connection between the first swinging member 20 and the fixing member 10.

[0045] Similarly, in order to realize the rotatable connection between the second swing member 30 and the first swing member 20, in an exemplary embodiment provided by the present disclosure, the second swing member 30 may be respectively formed with a second connecting shaft 31 on both sides, the first swing member 20 is formed with a second hinge hole 23, the second connecting shaft 31 is arranged corresponding to the second hinge hole 23 and is rotatably connected in the second hinge hole 23, and the central axis of the second connecting shaft 31 is colinear with the second swing axis Y. In this way, the second swing member 30 can swing around the second connecting shaft 31 under the drive of the driving assembly 40, and the second connecting shaft 31 is colinear with the second swing axis Y, so that the second swing member 30 can swing around the second swing axis Y.

[0046] In order to facilitate the swinging of the first swinging member 20 relative to the fixed member 10 and the swinging of the second swinging member 30 relative to the first swinging member 20, in the present disclosure, optionally, a first through hole 12 can be formed on the fixed member 10, and the first through hole 12 is located between the two first hinge holes 11; a second through hole 22 can be formed on the first swinging member 20, and the second through hole 22 is located between the second hinge holes 23; the second swinging member 30 is sequentially inserted into the first through hole 12 and the second through hole 22; the display screen is connected to the first end of the second swinging member 30; and the driving assembly 40 is connected to the second end of the second swinging member 30. In this way, during the swinging of the first swinging member 20 around the first swinging axis X, the first through hole 12 formed between the two first hinge holes 11 can provide an escape space for the swinging of the first swinging member 20, thereby avoiding the swinging of the first swinging member 20 from being restricted by the fixing member 10; similarly, during the swinging of the second swinging member 30 around the second swinging axis Y, the second through hole 22 formed between the two second hinge holes 23 can provide an escape space for the swinging of the second swinging member 30, thereby avoiding the swinging of the second swinging member 30 from being restricted by the first swinging member 20.

[0047] In order to facilitate the driving assembly 40 to drive the first swing member 20 and the second swing member 30, in the present disclosure, optionally, the display screen adjustment device 1 may further include a transmission assembly 50, the transmission assembly 50 includes a first transmission member 51 and a second transmission member 52, the first transmission member 51 is connected to the second swing member 30, and the second transmission member 52 is connected to the driving assembly 40, and the driving assembly 40 can drive the first transmission member 51 to rotate when driving the second transmission member 52 to move along the first direction, so that the first swing member 20 swings around the first swing axis X, and drives the second swing member 30 to swing around the first swing axis X, and the driving assembly 40 can drive the first transmission member 51 to rotate when driving the second transmission member 52 to move along the second direction, so that the second swing member 30 swings around the first swing axis Y. In other words, the driving assembly 40 can first drive the transmission assembly 50 to move, and then drive the first swing member 20 and the second swing member 30 to move through the movement of the transmission assembly 50, so as to achieve indirect driving of the second swing member 30 and the display screen.

[0048] The present disclosure does not limit the specific structure of the first transmission member 51 and the second transmission member 52. For example, in an exemplary embodiment provided by the present disclosure, the first transmission member 51 is a first ball gear, and the second transmission member 52 is a second ball gear. One of the first ball gear and the second ball gear has a plurality of spaced-apart protrusions, and the other of the first ball gear and the second ball gear has a plurality of spaced-apart recessed grooves. The first ball gear and the second ball gear are arranged opposite to each other and can mesh with each other, and both the first ball gear and the second ball gear have the freedom to swing around a first swing axis X and the freedom to swing around a second swing axis Y.

[0049] Specifically, when the angle of the display screen needs to be adjusted, since the driving component 40 is connected to the second ball gear, when the driving component 40 is started, it can drive the second ball gear to move in the first direction or the second direction. Since the second ball gear is meshed with the first ball gear, when the first ball gear moves in the first direction or the second direction, it can drive the second ball gear to swing around the first swing axis X or the second swing axis Y, thereby driving the second swing member 30 and the display screen connected to the second swing member 30 to swing, thereby adjusting the angle of the display screen.

[0050] It should be noted that the present disclosure does not limit the specific structure and quantity of the above-mentioned driving component 40. For example, the driving component 40 can be one, and the above-mentioned driving component 40 can drive the first swinging member 20 to swing around the first swing axis X, and can drive the second swinging member 30 to swing around the second swing axis Y. Alternatively, the above-mentioned driving component 40 can also include two driving mechanisms. For example, in an exemplary embodiment provided by the present disclosure, the driving component 40 can include a first driving mechanism 41 and a second driving mechanism 42. The first driving mechanism 41 is connected to the second swinging member 30, and can drive the first swinging member 20 to swing around the first swing axis X when the first driving mechanism 41 moves along the first direction, so that the second swinging member 30 swings around the first swing axis X. The second driving mechanism 42 is connected to the first driving mechanism 41, and can drive the second swinging member 30 to swing around the second swing axis Y when the second driving mechanism 42 moves along the second direction. Since the first driving mechanism 41 is connected to the second swinging member 30, and the first swinging member 20 is rotatably connected to the second swinging member 30, when it is necessary to drive the display screen to swing along the first direction, the first driving mechanism 41 can drive the second swinging member 30 to move when moving along the first direction, thereby driving the display screen connected to the second swinging member 30 to swing around the first swing axis X, thereby realizing the adjustment of the tilt angle of the display screen in the first direction. Similarly, when it is necessary to drive the display screen to move along the second direction, the second driving mechanism 42 moves along the second direction and drives the first driving mechanism 41 to move synchronously along the second direction. When the first driving mechanism 41 moves along the second direction, it can drive the second swinging member 30 to rotate around the second swing axis Y through the first swinging member 20, thereby realizing the adjustment of the tilt angle of the display screen in the second direction.

[0051] In other embodiments of the present disclosure, the first transmission member 51 and the second transmission member 52 may also be connected in transmission via a universal ball shaft or other structure, which can also achieve the above-mentioned effect.

[0052] The present disclosure does not limit the driving method and specific driving structure of the first driving mechanism 41. For example, Figure 1 to Figure 2As shown, the first driving mechanism 41 may include a first linear motor and a first mounting bracket 412. The first linear motor includes a first primary part 410 and a first secondary part 411. The first primary part 410 and the first secondary part 411 can be relatively displaced along the first direction when powered on. One of the first primary part 410 and the first secondary part 411 is connected to the second driving mechanism 42, and the other of the first primary part 410 and the first secondary part 411 is connected to the second swinging member 30. In this way, when the angle of the display screen needs to be adjusted, the first linear motor is started. At this time, the first primary part 410 and the first secondary part 411 are relatively displaced, so that the first primary part 410 or the first secondary part 411 connected to the second swinging member 30 drives the first swinging member 20 to swing around the first swing axis X when moving, thereby driving the second swinging member 30 and the display screen to swing, thereby adjusting the angle of the display screen.

[0053] In addition, in order to facilitate the connection between the first linear motor and the second transmission member 52 , a connecting plate 43 may be provided on a side of the second transmission member 52 close to the first linear motor, and the first primary part is connected to the connecting plate 43 .

[0054] It should be noted that the first linear motor should be a motor that can realize forward and reverse rotation, so as to realize the reciprocating swing of the display screen to meet the usage needs of users in different positions (such as the main driver or the co-driver).

[0055] It can be understood that, Figure 1 to Figure 2 As shown, the above-mentioned first primary part 410 may include a primary iron core and an armature winding, wherein the primary iron core has a plurality of salient pole cores as primary teeth, and the armature winding is wound on the primary teeth; the first secondary part 411 is composed of a plurality of secondary iron cores, permanent magnets and a fixed shaft, each secondary iron core has a yoke and a tooth, and the tooth of the secondary iron core corresponds to the tooth of the primary iron core, and when currents in different directions are passed into the electric drive winding, the relative displacement direction between the first primary part 410 and the first secondary part 411 can be controlled, thereby realizing the adjustment of the angle of the display screen.

[0056] In another embodiment provided in the present disclosure, the first driving mechanism 41 may also be a cylinder, and the telescopic rod of the cylinder is connected to the second swinging member 30. In this way, during the extension and retraction of the telescopic rod, the second swinging member 30 may be driven to swing forward or reversely, thereby driving the display screen to swing and adjusting the tilt angle of the display screen.

[0057] Alternatively, in another exemplary embodiment provided in the present disclosure, the first driving mechanism 41 may also be a rotary motor, a first gear is provided on the rotating shaft of the rotary motor, a first rack is formed on the side of the second swinging member 30 close to the rotary motor, and the first gear is meshed with the first rack. In this way, when the rotating shaft of the rotary motor rotates forward or reversely, it can drive the first rack meshed with the first gear to move, thereby driving the second swinging member 30 to swing, so as to adjust the angle of the display screen.

[0058] It should be noted that compared with rotary motors, linear motors have the following advantages: First, the structure is simple. Since linear motors do not require additional devices to convert rotary motion into linear motion, the structure of the system itself is greatly simplified, and the weight and volume are greatly reduced; second, the positioning accuracy is high. Where linear motion is required, linear motors can achieve direct transmission, thereby eliminating various positioning errors caused by intermediate links, so the positioning accuracy is high; third, the response speed is fast, the sensitivity is high, and the follow-up performance is good. It is easy for linear motors to support their movers with magnetic suspension, so that a certain air gap is always maintained between the mover and the stator without contact, thereby eliminating the contact friction resistance between the primary (stator) and the secondary (motor), thereby greatly improving the sensitivity, rapidity and follow-up performance of the system.

[0059] Alternatively, if Figure 1 to Figure 2 As shown, the first mounting frame 412 may include a first mounting plate 4121 and a first mounting ear 4122 protruding from the first mounting plate 4121, one of the first primary part 410 and the first secondary part 411 is connected to the first mounting ear 4122, and the first mounting plate 4121 is connected to the second driving mechanism 42 on one side away from the first mounting ear 4122.

[0060] For example, with respect to the implementation mode in which the first primary part 410 is installed on the first mounting ear 4122, at this time, the first primary part 410 and the first mounting frame 412 are in a relatively fixed state. Thus, when the above-mentioned first linear motor is running, the first secondary part 411 connected to the first primary part 410 can slide along the extension direction of the first primary part 410 under the action of the magnetic force, thereby driving the second swinging member 30 to swing.

[0061] For the implementation mode in which the first secondary part 411 is installed on the first mounting ear 4122, at this time, the first secondary part 411 and the first mounting frame 412 are in a relatively fixed state. In this way, when the above-mentioned first linear motor is running, the first primary part 410 connected to the first secondary part 411 can slide along the extension direction of the first secondary part 411 under the action of magnetic force, thereby driving the second swinging member 30 to swing.

[0062] Similarly, the present disclosure does not limit the specific driving method and driving structure of the second driving mechanism 42. For example, in the present disclosure, Figure 1 to Figure 2 As shown, the second driving mechanism 42 may include a second linear motor and a second mounting bracket 422, the second linear motor includes a second primary portion 420 and a second secondary portion 421, the second primary portion 420 and the second secondary portion 421 can be relatively displaced along the second direction when powered on, one of the second primary portion 420 and the second secondary portion 421 is connected to the first driving mechanism 41, and is used to drive the first driving mechanism 41 to move. When the second linear motor is started, under the action of the magnetic force, the second primary portion 420 and the second secondary portion 421 can be relatively displaced, thereby driving the first driving mechanism 41 connected to the second primary portion 420 or the second secondary portion 421 to move toward the second direction.

[0063] Similarly, if Figure 1 to Figure 2 As shown, the second driving mechanism 42 may further include a second mounting frame 422, the second mounting frame 422 includes a second mounting plate 4221 and a second mounting ear 4222 protruding from the second mounting plate 4221, one of the second primary portion 420 and the second secondary portion 421 is connected to the first driving mechanism 41, and the other of the second primary portion 420 and the second secondary portion 421 is connected to the second mounting ear 4222. The second mounting frame 422 can support and fix the second primary portion 420 or the second secondary portion 421, thereby facilitating the relative movement between the second primary portion 420 and the second secondary portion 421.

[0064] One of the second primary part 420 and the second secondary part 421 mentioned above can be connected to the side of the first mounting plate 4121 away from the first driving mechanism 41, so that when the second primary part 420 and the second secondary part 421 undergo relative displacement, the first mounting plate 4121 and the first driving mechanism 41 installed on the first mounting plate 4121 can be driven to move together.

[0065] Alternatively, in other embodiments provided in the present disclosure, the second driving mechanism 42 may also be any mechanism such as a cylinder, a telescopic rod, etc. that can drive the first driving mechanism 41. The implementation principle is the same as the description of the first driving mechanism 41 above, and the present disclosure will not elaborate on this.

[0066] In addition, it should be noted that, for the embodiment in which the display screen adjustment device 1 is used in the field of vehicle technology, the second mounting bracket 422 can be installed on the dashboard of the vehicle, thereby achieving relative fixation between the display screen adjustment device 1 and the dashboard.

[0067] The present disclosure does not limit the connection method between the second mounting bracket 422 and the instrument panel. It can be connected to the instrument panel in a detachable manner such as snap-on, fastener connection, etc., or it can be connected to the instrument panel in a non-detachable manner such as welding, one-piece molding, etc.

[0068] Alternatively, if Figure 1 to Figure 2 As shown, the display screen adjustment device 1 may further include a display screen mounting seat 60, which is connected to the second swinging member 30, and the display screen mounting seat 60 is used to mount the display screen. Similarly, the display screen may be connected to the second swinging member 30 in a detachable manner such as the above-mentioned snap connection. For example, in an exemplary embodiment provided by the present disclosure, a plurality of fixing holes 61 may be provided on the display screen mounting seat 60, and fasteners may be inserted into the fixing holes 61 to fix the display screen on the display screen mounting seat 60. Alternatively, the display screen may be connected to the second swinging member 30 in a non-detachable manner such as welding or integral molding, which is not limited by the present disclosure.

[0069] The second aspect of the present disclosure provides a display screen assembly, including a display screen and the above display screen adjustment device 1, wherein the display screen is connected to the second swinging member 30 of the display screen adjustment device 1. The display screen assembly has all the beneficial effects of the above display screen adjustment device 1, which will not be described in detail in the present disclosure.

[0070] The display screen and display screen assembly provided by the present disclosure can be used in any scenario. For example, the third aspect of the present disclosure provides a vehicle, including the above display screen adjustment device 1 or the above display screen assembly. The vehicle has all the beneficial effects of the above display screen adjustment device 1 and display screen assembly, which will not be elaborated in the present disclosure.

[0071] Alternatively, if Figure 3 As shown, the vehicle further includes a face recognition module 70 and a controller 80, and the controller 80 is respectively connected to the face recognition module 70 and the drive assembly 40 by signal. In this way, by setting the face recognition module 70, during the user's use, the face recognition module 70 can recognize the face information and send it to the controller 80. After receiving the face information, the controller 80 controls the drive assembly 40 to move, thereby adjusting the display screen to a suitable angle without manual adjustment, and providing a better user experience.

[0072] For the embodiment in which the driving assembly 40 includes a first linear motor and a second linear motor, the controller 80 may be electrically connected to the first linear motor and the second linear motor, respectively.

[0073] Alternatively, if Figure 3As shown, the vehicle may further include a photosensitive module 90, which is signal-connected to the controller 80. By providing the photosensitive module 90, the light around the display screen can be collected, thereby avoiding the situation in which the driver is dazzled by reflections during the adjustment of the tilt angle of the display screen, thereby improving the comfort of the user during use.

[0074] In the present disclosure, in order to improve the collection effect of the above-mentioned face recognition module 70 and photosensitive module 90, the face recognition module 70 and the photosensitive module 90 can be set on the display screen. In this way, when the user looks at the display screen, the face recognition module 70 can quickly collect facial information, and the photosensitive module 90 set on the display screen can also more accurately detect the lighting conditions of the display screen, thereby making quick and precise adjustments to the angle of the display screen.

[0075] Furthermore, by arranging the face recognition module 70 and the photosensitive module 90 on the display screen, the structure of the display assembly can be further simplified by utilizing the power supply, wiring harness and other structures within the display screen.

[0076] Alternatively, in another embodiment provided by the present disclosure, for an embodiment in which the display screen adjustment device 1 includes a display screen mounting bracket 60, the above-mentioned face recognition module 70 and photosensitive module 90 can both be arranged on the display screen mounting bracket 60. In this way, the face recognition module 70 and the photosensitive module 90 can also have a better acquisition viewing angle, thereby more accurately detecting the position of the face and the light conditions of the display screen, reducing the acquisition error, so that the controller 80 can make a more accurate judgment.

[0077] The signal connection mentioned above can be achieved through a wired connection such as a wire, or can be achieved through a wireless connection such as Bluetooth, a wireless network, etc., and the present disclosure does not impose any restrictions on this.

[0078] In order to facilitate the understanding of the present solution, the specific cooperation relationship between the controller 80 and the face recognition module 70, the photosensitive module 90, the first drive mechanism 41 and the second drive mechanism 42 is described in detail. Specifically, the face recognition module 70 sends the face information to the controller 80 after collecting it, and the controller 80 controls the movement of the first drive mechanism 41 and / or the second drive mechanism 42 according to the face information. Specifically, when it is necessary to adjust the inclination angle of the display screen in the second direction, the second linear motor starts and drives the second secondary part 421 to move in the second direction, thereby driving the first linear motor connected to the second secondary part 421 to move in the second direction. During the movement of the first linear motor in the second direction, it can drive The second transmission member 52 moves along the second direction, thereby driving the first transmission member 51, the second swinging member 30 and the display screen connected to the second swinging member 30 to swing around the second swinging axis Y, thereby adjusting the inclination angle of the display screen in the second direction; similarly, when it is necessary to adjust the inclination angle of the display screen in the first direction, the first linear motor can be started to move along the first direction. When the first linear motor moves along the first direction, it drives the second transmission member 52 to move along the first direction, driving the first transmission member 51 and the first swinging member 20 to swing around the first swinging axis X, thereby driving the second swinging member 30 and the display screen connected to the second swinging member 30 to swing around the first swinging axis X, thereby adjusting the angle of the display screen in the first direction.

[0079] After the adjustment is completed, the photosensitive module 90 collects the light information around the screen and transmits it to the controller 80. The controller 80 determines whether the display screen has a reflection problem based on the light information. If there is no reflection problem, there is no need to control the movement of the first linear motor and / or the second linear motor. If a reflection problem occurs, the first linear motor and / or the second linear motor is controlled to move until the reflection problem disappears.

[0080] In addition, the display screen mentioned above can be any electronic product with a display screen, such as a mobile phone, a tablet computer, etc., and the present disclosure does not limit this.

[0081] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0082] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0083] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
