Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The emergency condition prompting system based on the vehicle-mounted display terminal and the vehicle are described below with reference to the accompanying drawings.
Fig. 1 is a block diagram of an emergency condition prompting system based on a vehicle-mounted display terminal according to an embodiment of the invention. As shown in fig. 1, the system includes: a display terminal 100, a parameter detection assembly 200, and a controller 300.
The parameter detecting assembly 200 is used to detect a driving parameter of a vehicle. The controller 300 is respectively connected with the parameter detecting component 200 and the display terminal 100, and when the controller 300 judges that the vehicle is in an emergency condition according to the running parameters of the vehicle, the display terminal 100 is controlled to send out prompt information.
Further, in an embodiment of the present invention, the controller 300 may be integrated within the display terminal 100. The emergency condition may include: a sharp turning condition, an emergency accelerating condition and an emergency braking condition.
Specifically, during the running process of the vehicle, the parameter detecting component 200 detects the running parameters of the vehicle in real time, such as the vehicle speed, the steering wheel rotation angle of the vehicle, the depth of an accelerator pedal, the depth of a brake pedal, and the like, and then the controller determines whether the vehicle is in an emergency condition according to the running parameters of the vehicle, for example, whether the vehicle is in an emergency acceleration condition may be determined according to the vehicle speed and the depth of the accelerator pedal. If the vehicle is in the emergency working condition, the display terminal 100 is controlled to send out corresponding prompt information to warn the driver that improper operation is currently carried out, so that the driver is reminded of driving safely, and the driving safety is improved. And, because the controller is integrated in display terminal, the controller can acquire the parameter of going of vehicle fast, need not to upload the parameter of going of vehicle to the server, gathers, analysis and feedback etc. to can indicate the driver fast when the driver improper driving operation appears.
According to one embodiment of the invention, as shown in FIG. 2, the parameter detection component 200 may include: a steering wheel angle detection module 201 and a vehicle speed detection module 202. The steering wheel angle detecting module 201 is configured to detect a steering wheel rotation angle of the vehicle, and the vehicle speed detecting module 202 is configured to detect a vehicle speed of the vehicle.
Further, as shown in fig. 2, the emergency condition prompting system based on the vehicle-mounted display terminal may further include: for adjusting the actuator 400 of the display terminal 100. The controller 300 is further configured to control the display terminal 100 to rotate along with the steering wheel rotation angle through the actuator 400 when it is determined that the vehicle is currently in a sharp turn condition according to the vehicle speed and the steering wheel rotation angle of the vehicle.
Further, as shown in fig. 2, the emergency condition prompting system based on the vehicle-mounted display terminal may further include: the calculating module 500, the calculating module 500 is configured to calculate an angle that the display terminal 100 rotates along with the steering wheel rotation angle, wherein the calculating module 500 obtains an angle θ that the display terminal 100 rotates along with the steering wheel rotation angle according to the following formula:
Figure BDA0001613737430000051
wherein, XmaxIs the maximum angle of rotation of the steering wheel, θmaxThe maximum rotation angle of the display terminal, X is the actual rotation angle of the steering wheel, and θ is the angle at which the display terminal rotates following the rotation angle of the steering wheel.
Specifically, the actuator 400 can rotate the display terminal left and right, and the actuator 400 can adjust the display terminal 200 to rotate left and right, which can be seen in fig. 3a-3 b. In the running process of the vehicle, the vehicle speed detection component 201 detects the vehicle speed of the vehicle in real time, the steering wheel rotation angle detection component 202 detects the steering wheel rotation angle of the vehicle in real time, and the controller 300 collects and judges the vehicle speed and the steering wheel rotation angle of the vehicle in real time. If the controller 300 determines that the steering wheel rotates by more than a first preset angle within a preset time according to the steering wheel rotation angle and the vehicle speed of the vehicle is greater than a preset vehicle speed, it is determined that the vehicle is currently in a sharp turning condition, and the controller 300 controls the display terminal 100 to rotate along with the steering wheel rotation angle through the control execution mechanism 400. The preset time, the first preset angle and the preset vehicle speed can be preset according to the specific conditions of the vehicle (such as the wheel axle distance, the transmission ratio of a steering wheel and a transmission shaft and the like).
In principle, the rotation angle θ of the display terminal 100 only needs to be 0-90 °, and does not need to be the same as the rotation angle of the steering wheel, and the controller 300 can specifically be according to the formula
Figure BDA0001613737430000061
Determining a rotation angle θ of the display terminal, wherein the rotation direction of the display terminal 100 is the same as the rotation direction of the steering wheel, as shown in fig. 3a-3b, the rotation direction is clockwise as a positive angle, the rotation direction is counterclockwise as a negative angle, the display terminal 100 is in an initial state when in a vertical state or a vertical screen state, and the rotation angle is 0 °. The controller 300 may control the actuator 400 according to the current state (landscape state or portrait state) of the display terminal 100, the rotation angle θ and the rotation direction, and the actuator 400 controls the display terminal 100 to rotate along with the rotation angle and direction of the steering wheel and maintain the current state after rotating to the required position, so as to warn the driver that improper operation is currently performed, thereby improving the driving safety.
When the steering wheel rotation angle detecting component 202 detects that the steering wheel rotation angle is smaller than the second preset angle, it is determined that the sharp turning condition reminding is finished, and the controller 300 adjusts the display terminal 100 to the initial position through the executing mechanism 400. The second preset angle can be preset according to the specific situation of the vehicle, for example, the second preset angle can be preset by referring to the return angle of the steering lamp.
According to an embodiment of the present invention, the controller 300 may be further configured to control the dynamic effect map in the display interface of the display terminal 100 to rotate along with the turning angle of the steering wheel when it is determined that the vehicle is currently in the sharp turning condition according to the vehicle speed and the turning angle of the steering wheel.
Specifically, when it is determined that the vehicle is currently in a sharp turning condition, the controller 300 may also control the display interface of the display terminal 100 to display the dynamic effect map to remind the driver, for example, the display interface displays an animation of the vehicle, and the animation rotates along with the rotation angle of the steering wheel to warn the driver of a current improper operation. When the steering wheel rotation angle detection assembly 202 detects that the steering wheel rotation angle is smaller than the second preset angle, it is judged that the sharp turning condition reminding is finished, and the display interface returns to normal. According to an embodiment of the present invention, as shown in fig. 2, the parameter detection component 200 may further include: an accelerator pedal depth detection component 203. The accelerator pedal depth detection component 203 is connected to the controller 300, and the accelerator pedal depth detection component 203 is configured to detect the accelerator pedal depth of the vehicle, where the controller 300 controls the display interface of the display terminal 100 to display in a backward 3D manner when determining that the vehicle is currently in an emergency acceleration condition according to the accelerator pedal depth and the vehicle speed of the vehicle.
Specifically, during the running process of the vehicle, the vehicle speed detection component 202 detects the vehicle speed of the vehicle in real time, the accelerator pedal depth detection component 203 detects the accelerator pedal depth of the vehicle in real time, and the controller 300 determines the vehicle speed and the accelerator pedal depth of the vehicle. If the depth of the accelerator pedal is greater than the preset depth of the accelerator pedal, and the acceleration of the vehicle (the ratio of the vehicle speed change value to the preset time within the preset time) is greater than the preset acceleration, the controller 300 determines that the vehicle is in an emergency acceleration state, and both the preset depth of the accelerator pedal and the preset acceleration can be preset according to the actual condition of the vehicle. At this time, the controller 300 controls the display interface of the display terminal to display in a backward 3D manner to warn the driver of the current improper driving operation, thereby improving the driving safety. When the display interface is displayed in a backward 3D mode, the display interface is wholly stripped from the display area, the lower boundary is kept still, the upper boundary moves outwards of the screen, part of content in the interface overflows the interface and is not displayed, the main interface forms the effect of one piece of paper, the whole body looks like the effect of inclining the main interface to the back of the vehicle to form the screen, and the backward effect is achieved. And when the depth of the accelerator pedal is less than or equal to the preset depth of the accelerator pedal, or the acceleration of the vehicle is less than or equal to the preset acceleration, the display interface returns to normal.
According to an embodiment of the present invention, the controller 300 may be further configured to control the display terminal to turn backward by a preset angle with respect to the driver through the actuator 400 when the vehicle is currently in the emergency acceleration condition according to the depth of the accelerator pedal and the vehicle speed of the vehicle. The preset angle may be preset according to actual conditions, for example, 60 °.
Specifically, when the controller 300 determines that the vehicle is in the emergency acceleration state, the controller 300 may also control the display terminal to turn backward relative to the driver by using a center line perpendicular to a side of the display terminal as an axis through the actuator 400, that is, the upper portion of the entire display terminal turns backward and the lower portion turns forward, so that the entire display terminal presents a backward tilting effect relative to the driver, thereby warning the driver of improper operation. When the accelerator pedal depth is less than or equal to the preset accelerator pedal depth, or the acceleration of the vehicle is less than or equal to the preset acceleration, the controller 300 adjusts the display terminal 100 to the initial position through the actuator 400. It can be understood that the controller 300 determines whether the vehicle is in an emergency acceleration state according to two data of the measured accelerator pedal depth and the measured vehicle speed, so as to avoid the situation of misjudgment caused by the accelerator being stepped on in a neutral gear or the abnormal vehicle speed signal.
According to an embodiment of the present invention, as shown in fig. 3, the parameter detection component 200 may further include: a brake pedal depth detection component 204. The brake pedal depth detection component 204 is connected to the controller 300, and the brake pedal depth detection component 204 is configured to detect a brake pedal depth of the vehicle, where the controller 300 controls the display interface of the display terminal 100 to display in a forward-tilting 3D manner when judging that the vehicle is currently in an emergency braking condition according to the brake pedal depth and a vehicle speed of the vehicle.
Specifically, during the running of the vehicle, the vehicle speed detection component 300 detects the vehicle speed of the vehicle in real time, the brake pedal depth detection component 204 detects the brake pedal depth of the vehicle in real time, and the controller 300 judges the vehicle speed and the brake pedal depth of the vehicle. If the depth of the brake pedal is greater than the preset depth of the brake pedal, and the deceleration of the vehicle (the ratio of the vehicle speed change value to the preset time within the preset time) is greater than the preset deceleration, the controller 300 determines that the vehicle is in an emergency braking state, and both the preset depth of the brake pedal and the preset deceleration can be preset according to the actual condition of the vehicle. At this time, the controller 300 controls the display interface of the display terminal to display in a forward 3D tilting manner to warn the driver of the current improper driving operation, thereby improving the driving safety. And when the depth of the brake pedal is less than or equal to the preset depth of the accelerator pedal, or the deceleration of the vehicle is less than or equal to the preset deceleration, the display interface returns to normal. When the display interface is displayed in a forward-tilting 3D mode, the whole display interface is stripped from the display area, the lower boundary is kept still, the upper boundary moves towards the inside of the screen, the main interface forms the effect same as a piece of paper, and the background of the paper is added, so that the whole display interface looks like the effect of the main interface tilting towards the front of the vehicle and entering the screen, and the forward-tilting effect is achieved.
According to an embodiment of the present invention, the controller 300 may be further configured to control the display terminal to turn forward by a preset angle relative to the driver through the actuator 400 when the vehicle is currently in the emergency acceleration condition according to the depth of the accelerator pedal and the vehicle speed of the vehicle. The preset angle may be preset according to actual conditions, for example, 60 °.
Specifically, the controller 300 may also control the display terminal to turn forward relative to the driver by using a center line perpendicular to a side of the display terminal as an axis through the actuator 400, that is, the upper portion of the entire display terminal turns forward and the lower portion turns backward, so that the entire display terminal presents a forward tilting effect relative to the driver, thereby warning the driver of current improper operation. When the brake pedal depth is less than or equal to the preset accelerator pedal depth, or the deceleration of the vehicle is less than or equal to the preset deceleration, the controller 300 adjusts the display terminal 100 to the initial position through the actuator 400. It can be understood that the controller 300 determines whether the vehicle is in an emergency braking state according to two data of the depth of the brake pedal and the vehicle speed of the vehicle, so as to avoid the situation of misdetermination caused by deep stepping on the vehicle due to in-situ braking or abnormal vehicle speed signal.
It is understood that in the embodiment of the present invention, the steering wheel angle detecting assembly 201 may include a steering wheel angle sensor, the vehicle speed detecting assembly 202 may include a wheel speed sensor, the accelerator pedal depth detecting assembly 203 may include an accelerator pedal depth sensor, and the brake pedal depth detecting assembly 204 may include a brake pedal depth sensor.
Except that the driver can be reminded when the vehicle is in an emergency working condition in the mode, the driver can also be reminded in the following mode.
According to an embodiment of the present invention, the display terminal 100 may include a voice module, and the controller 300 further controls the display interface of the display terminal to emit a rotating and flashing light and controls the voice module to emit a voice prompt message when determining that the vehicle is currently in the emergency condition according to the driving parameters of the vehicle.
That is, when the vehicle is in a sharp turning condition, the controller 300 controls the display terminal 100 to rotate along with the rotation angle of the steering wheel, and also controls the display interface of the display terminal 100 to emit light that flashes in a rotating manner, and controls the voice module to emit voice such as "please pay attention to driving safety when the vehicle is in the sharp turning condition at present"; when the vehicle is in the emergency acceleration condition, the controller 300 controls the display interface of the display terminal 100 to display in a backward 3D manner, and also controls the display interface of the display terminal 100 to emit light that flashes in a rotating manner, and controls the voice module to emit a voice such as "please pay attention to driving safety when the vehicle is currently in the emergency acceleration condition"; when the vehicle is in the emergency braking condition, the controller 300 controls the display interface of the display terminal 100 to display in a forward-tilting 3D manner, and also controls the voice module to send a voice such as "currently in the emergency braking condition, please pay attention to driving safety".

Specifically, in the driving process of the vehicle, the controller 300 may determine whether the vehicle is in a turning condition by obtaining the map information in the navigation module, and if the vehicle is in the turning condition, the controller 300 may control the display terminal 100 to rotate by a preset angle according to the turning direction by controlling the execution mechanism 400, so as to prompt the driver to turn. It can be understood that, if the controller 300 determines that the vehicle is currently in a sharp turning condition according to the vehicle speed and the steering wheel rotation angle of the vehicle, even if the controller 300 determines whether the vehicle is in a turning condition according to the map information, the controller 300 preferentially controls the display terminal 100 to rotate along with the steering wheel rotation angle through the actuator 400 to alert the driver that the vehicle is currently in a sharp turning condition.
The actuator 400 is described below with reference to fig. 4-17.

The rotating bracket engagement surface 21 may extend rearward to be formed substantially as an engagement surface opened on the rear side, and may be substantially tapered from the forward rearward, rotating bracket engagement surface 21.
Here, the "rear surface of the display screen 1" refers to a surface of the display screen 1 on a side away from the user when the user uses the display screen 1, and the "front surface of the display screen 1" refers to a surface of the display screen 1 on a side close to the user when the user uses the display screen 1.

According to the display terminal 100 provided by the embodiment of the invention, the first driving device 32 and the movable power transmission part 33 are arranged, and the power transmission part 33 is movably connected with the rotating support 2, so that the first driving device 32 drives the power transmission part 33 to move to drive the display screen 1 to swing at an angle through the rotating support 2, and therefore, the electric adjustment of the placement angle of the display screen 1 is realized, the display screen 1 is subjected to proper adjustment force and keeps proper adjustment speed in the adjustment process, the display terminal 100 can be protected to a certain extent, meanwhile, the intelligent degree of the display terminal 100 is improved, and the display terminal 100 is simple in structure and convenient to realize.
Specifically, the adjuster engagement surface 31 and the rotating bracket engagement surface 21 together define a chamber 100a, a power transmission member 33 and a first driving device 32 are provided in the chamber 100a, and one end of the power transmission member 33 is ball-hinged to the rotating bracket 2. From this, to a certain extent, cavity 100a has certain dustproof, waterproof effect to can include first drive arrangement 32 and power transmission spare 33, simultaneously because power transmission spare 33's one end and rotation support 2 ball joint, make power transmission spare 33 and rotation support 2 between have nimble degree of freedom, guaranteed display screen 1 wobbling reliability.
For example, in the example of fig. 9 and 10, the ball 331 may be disposed at the end of the power transmission member 33, the ball 331 may be formed in a spherical structure, the ball mounting cavity 22 may be formed on the rotating bracket 2, and the ball 331 is correspondingly fitted in the ball mounting cavity 22 to realize the ball hinge between the power transmission member 33 and the rotating bracket 2. The first driving device 32 can drive the power transmission member 33 during operation, so that the distance between the one end of the power transmission member 33 and the rear surface of the adjuster 3 is changed, and the power transmission member 33 can drive the display screen 1 to swing relative to the adjuster 3 by rotating the bracket 2, so that the placement angle of the display screen 1 is convenient for a user to watch.
Of course, the ball 331 may also be disposed on the rotating bracket 2, the ball mounting cavity 22 is correspondingly formed on the one end of the power transmission member 33, and the ball 331 is correspondingly fitted in the ball mounting cavity 22, so as to realize the ball hinge between the power transmission member 33 and the rotating bracket 2.
Further, the number of the first driving devices 32 and the number of the power transmission members 33 are two, the two power transmission members 33 are respectively matched with the two first driving devices 32, one of the two first driving devices 32 is suitable for driving the display screen 1 to swing left and right through the corresponding power transmission member 33, and the other one of the two first driving devices 32 is suitable for driving the display screen 1 to swing up and down through the corresponding power transmission member 33. For example, as shown in fig. 4, 9 and 10, the first driving device 32 may drive the corresponding power transmission member 33 when operating, so that the distance between the one end of the power transmission member 33 and the rear surface of the adjuster 3 is changed, and the power transmission member 33 may drive the display screen 1 to swing relative to the adjuster 3 by rotating the bracket 2, so that the display screen 1 is placed at an angle convenient for the user to view. One of the two first driving devices 32 drives the display screen 1 to swing left and right through the corresponding power transmission part 33, and the other one of the two first driving devices 32 drives the display screen 1 to swing up and down through the corresponding power transmission part 33, so that multidirectional electric adjustment of the placement angle of the display screen 1 is realized, the use of a user is greatly facilitated, and the experience effect of the user is improved; when display terminal 100 is applied to the vehicle, can specifically adjust two first drive arrangement 32's running state according to the personnel's on the main and auxiliary driving position watching demand, make display screen 1 through from top to bottom, the right-and-left hunting obtains suitable angle of placing, the multi-direction electrical control that display screen 1 placed the angle has been realized promptly, make display screen 1 in accommodation process, receive suitable regulation dynamics and keep suitable regulation rate, to a certain extent, can protect display terminal 100, the intelligent degree of display terminal 100 has been promoted simultaneously, be convenient for simultaneously on the main and auxiliary driving position personnel watch.
Wherein, two first driving devices 32 may be fixedly installed on the wall surface of the chamber 100a, for example, two first driving devices 32 may be fixedly installed on the regulator 3; the two first driving devices 32 may be controlled by a combination switch. For example, the combination switch includes two switches, each switch controls one first driving device 32 and each switch may have three control states, which are a first control state, a second control state and a third control state; when the switch is in the first control state, the corresponding first driving device 32 may stop operating, when the switch is in the second control state, the corresponding first driving device 32 may rotate in the forward direction, and at this time, the corresponding power transmission member 33 may move backward, so that the display screen 1 may swing toward one side where the power transmission member 33 is located with respect to the central axis of the rotating bracket 2, and when the switch is in the third control state, the corresponding first driving device 32 may rotate in the reverse direction, and at this time, the corresponding power transmission member 33 may move forward, so that the display screen 1 may swing toward one side opposite to one side where the power transmission member 33 is located with respect to the central axis of the rotating bracket 2. Wherein, the switch can be selected as a rocker switch. Here, it should be noted that "forward" and "reverse" are both relative concepts.
Of course, the combination switch may also be a virtual switch. For example, the combination switch may be a virtual key on the display screen. But is not limited thereto.
It is understood that the two first driving devices 32 may be operated independently or in a linkage manner. For example, the operating states of the two first driving devices 32 may not affect each other, and the operating state of one of the two first driving devices 32 may not affect the operating state of the other of the two first driving devices 32; alternatively, the operating states of the two first driving devices 32 may be influenced by each other, and the operating state of one of the two first driving devices 32 may be adaptively adjusted according to the operating state of the other of the two first driving devices 32.
Alternatively, the adjuster engagement surface 31 and the rotation bracket engagement surface 21 are formed as spherical surfaces, thereby facilitating multi-directional adjustment of the display screen 1 with respect to the adjuster 3. Of course, it is also possible that the adjuster engagement surface 31 is formed in a spherical surface and the rotating bracket engagement surface 21 is not a spherical surface; alternatively, the rotating bracket engagement surface 21 is formed as a spherical surface, and the adjuster engagement surface 31 is not a spherical surface. Therefore, various matching modes are provided between the adjustor 3 and the rotating bracket 2, the display screen 1 can be adjusted in multiple directions relative to the adjustor 3 conveniently through the matching of the adjustor matching surface 31 and the rotating bracket matching surface 21, and the diversity of the display terminal 100 is improved, so that the practical application is better met.
For example, when the adjuster mating surface 31 is formed as a spherical surface and the rotating bracket mating surface 21 is not a spherical surface, the rotating bracket mating surface 21 may be formed as a conical surface or other aspheric curved surface, and the rotating bracket mating surface 21 may be located outside the adjuster mating surface 31, and the adjuster mating surface 31 and the rotating bracket mating surface 21 may cooperate to achieve multi-directional adjustment of the display screen 1 with respect to the adjuster 3.
In alternative embodiments of the invention, as shown in fig. 4, 9 and 10, the line between the said one end of the two power transmission members 33 and the centre of the display screen 1 is at an angle of 90 °. That is, a line connecting the projections of the one ends of the two power transmission members 33 and the projection of the center of the display screen 1 on the first plane 100b forms an angle of 90 °, wherein the first plane 100b is a plane perpendicular to the central axis of the display terminal 100 extending in the front-rear direction. For example, as shown in fig. 9 and 10, the display screen 1 is located at its initial position, the display screen 1 is disposed coaxially with the rotating bracket 2, and a line connecting the projection of the above-mentioned one end of the two power transmission members 33 and the projection of the center of the rotating bracket 2 on the first plane 100b forms an angle of 90 °, thereby further ensuring that multi-directional adjustment of the placement angle of the display screen 1 can be achieved only by the two power transmission members 33.
Further, the display screen 1 is a rectangular screen, and the one ends of the two power transmission members 33 are respectively located at the middle positions of the long side and the short side of the display screen 1. That is, the one end of one of the two power transmission members 33 is disposed to face the perpendicular bisector of the short side of the display screen 1 in the front-rear direction, and the one end of the other of the two power transmission members 33 is disposed to face the perpendicular bisector of the long side of the display screen 1 in the front-rear direction. For example, in the examples of fig. 4, 9, and 10, the long side of the display screen 1 may be horizontally disposed in the left-right direction, and the short side of the display screen 1 may be vertically disposed in the up-down direction, because the one end of the one of the two power transmission members 33 is disposed opposite to the perpendicular bisector of the short side of the display screen 1 in the front-back direction, and the one end of the other of the two power transmission members 33 is disposed opposite to the perpendicular bisector of the long side of the display screen 1 in the front-back direction, when the one of the two power transmission members 33 moves, the display screen 1 may swing in the left-right direction, and when the other of the two power transmission members 33 moves, the display screen 1 may swing in the up-down direction, so that the display screen 1 may be quickly adjusted to a proper placement angle by the two power transmission.
Alternatively, the actuator 3 is formed with a guide groove (not shown) to be movably engaged with the power transmitting member 33, and the power transmitting member 33 is moved along the guide groove in the corresponding guide groove. Wherein, the guiding groove can be formed by the surface of the regulator 3 which limits the chamber 100a and is concave outwards, and the power transmission piece 33 can be matched with the guiding groove, so that the guiding groove can play the role of limiting and guiding to a certain extent. Here, it should be noted that the direction "outward" refers to a direction away from the center of the chamber 100 a.
Specifically, as shown in fig. 10, the two power transmission members 33 are racks, each first driving device 32 has a first output shaft 321, a free end of the first output shaft 321 has a meshing tooth matched with the rack, so that a gear transmission mechanism can be formed between the first output shaft 321 and the racks, and the first driving device 32 operates, the first output shaft 321 rotates, and thus the corresponding rack can be driven to move forwards or backwards. Therefore, the transmission between the first driving device 32 and the power transmission member 33 is accurate and reliable, and the structure is compact.
Alternatively, the two power transmission members 33 are arc-shaped racks that fit the spherical adjuster mating surface 31. For example, in the example of fig. 10, two racks are opposite to each other, the engaging teeth on the two racks may be opposite to each other, and the two racks may be symmetrically disposed, each rack is formed in an arc structure protruding toward a direction away from each other, and then the first output shafts 321 of the two first driving devices 32 may be disposed at parallel intervals, thereby further saving the occupied space and improving the space utilization. Moreover, the power transmission member 33 is set to be of an arc structure, so that the movement of the one end of the power transmission member 33 is adapted to the swing of the rotating bracket 2, and the power transmission member 33 can smoothly drive the rotating bracket 2 to swing when moving.
Of course, both power transmission members 33 may also be formed as arc-shaped racks each projecting in a direction away from the center of the regulator 3. For example, the engaging teeth of the two racks may be disposed opposite to each other inside and outside the central axis of the adjuster 3 extending in the front-rear direction, and each power transmission member may be formed in an arc-shaped configuration so as to allow the movement of the one end of the power transmission member 33 to be adapted to the swing of the rotating bracket 2. It can be understood that the specific shape and arrangement of the two power transmission members 33 can be specifically set according to the matching between the adjuster 3 and the rotating bracket 2, but not limited thereto, only one power transmission member 33 needs to be moved to drive the display screen 1 to swing left and right, and the other power transmission member 33 needs to be moved to drive the display screen 1 to swing up and down.
In some embodiments of the present invention, the rotating bracket mating surface 21 and the adjuster mating surface 31 are both formed as spherical surfaces, the rotating bracket mating surface 21 covers the outside of the adjuster mating surface 31, the rotating bracket mating surface 21 has an extension portion 211 extending toward the adjuster mating surface 31, and the rotating bracket mating surface 21 is in contact with the adjuster mating surface 31 through the extension portion 211. For example, as shown in fig. 7 to 10, the extension portion 211 may extend inward to contact the adjuster engagement surface 31, so that the rotating bracket engagement surface 21 may contact the adjuster engagement surface 31 only through the extension portion 211, thereby reducing the contact area between the rotating bracket engagement surface 21 and the adjuster engagement surface 31, and facilitating the assembly of the rotating bracket 2 and the adjuster 3.
Wherein the extension 211 may be located at a free end of the rotating bracket mating surface 21. For example, in the example of fig. 8, the extension portion 211 is located at the rear end of the rotating bracket engagement surface 21, thereby further facilitating the assembly of the rotating bracket 2 with the adjuster 3.
Further, as shown in fig. 4, 12 and 13, one side (for example, the rear side in fig. 4) of the regulator 3 that is far away from the rotating bracket 2 is provided with a rotating device 4, and the rotating device 4 is used for driving the display screen 1 to rotate in the plane where the display screen 1 is located, so that the display screen 1 can be switched between the horizontal screen position and the vertical screen position, and thus, image resources such as pictures and video screens on the display screen 1 can be displayed in an equal proportion and in a full screen, thereby better taking into account the personal use habits of users, and further improving the experience effect of users.

Here, the phrase "the rotation shaft 43 and the rotation disk 42 are fixedly connected" means that there is no relative movement between the rotation shaft 43 and the rotation disk 42 after the rotation device 4 is assembled.
For example, in the example of fig. 12-14, the display terminal 100 may be fixedly mounted on a vehicle by the fixing base 41 to enable mounting of the display terminal 100; the mounting hole 41a penetrates through the front end surface and the rear end surface of the fixing seat 41 in the axial direction of the fixing seat 41, wherein the fixing seat 41 may include a bracket 413 and an end cover 414, an installation space may be defined in the bracket 413, the second driving device 411 may be installed in the installation space, the end cover 414 may be disposed at the front end of the bracket 413, an accommodation space may be defined between the end cover 414 and the bracket 413, the accommodation space may be located at the lower side of the mounting hole 41a, and the transmission mechanism 412 is located in the accommodation space.

A through center hole is formed on the rotation shaft 43, so that the rotation shaft 43 can be sleeved on the rotation column 421 and the rotation shaft 43 is located between the installation hole 41a and the rotation column 421, thereby saving the occupied space.
When the second driving device 411 works, the second driving device 411 cooperates with the transmission mechanism 412 to drive the transmission mechanism 412 to operate, and the rotating shaft 43 cooperates with the transmission mechanism 412, so that the transmission mechanism 412 can drive the rotating shaft 43 to rotate, and the rotating shaft 43 can drive the display screen 1 to rotate through the rotating disc 42 and the adjuster 3, thereby enabling the display screen 1 to realize electric switching between the horizontal screen position and the vertical screen position.
Wherein, can be relatively up-and-down, horizontal hunting between regulator 3 and the rotation support 2 for the position of overlap portion between regulator fitting surface 31 and the rotation support fitting surface 21, the shape changes, and in the central axis pivoted direction that extends around display terminal 100 along the fore-and-aft direction, can unable relative motion between regulator 3 and the rotation support 2, thereby guaranteed that rotary device 4 can pass through regulator 3, rotation support 2 drives display screen 1 and rotates in the plane at display screen 1 place, realize the switching of horizontal screen and vertical screen.

It is understood that the rotation direction of the rotation disk 42, and thus the rotation direction of the display screen 1, may be controlled by controlling the rotation direction of the second output shaft 411 a; meanwhile, the rotation angle of the rotation disk 42 may be controlled by controlling the rotation angle of the second output shaft 411a, thereby controlling the rotation angle of the display screen 1. For example, the rotation angle of the second output shaft 411a at a time may be set to a fixed value, so that the rotation angle of the display screen 1 at a time is 90 °, further facilitating the use of the user.
