Description

Technical Field

[0001] This application relates to the field of vehicle accessories, and more particularly to a display device and a vehicle. Background Technology

[0002] A car rear-seat panoramic screen typically refers to a multimedia display device installed on the roof of the rear seats of a car. As a core component of the rear-seat entertainment system, it provides rear passengers with a rich audio-visual experience.

[0003] The panoramic sunroof consists of a base, a display screen, and a drive structure. The base connects to the vehicle roof, and the display screen is hinged to the base. The drive structure is used to extend or retract the base relative to the vehicle roof. When the display screen is extended, there is a certain angle between the display screen and the vehicle roof. When the display screen is retracted, it covers the vehicle roof to avoid occupying interior space. However, during the retraction process, the angle between the display screen and the vehicle roof gradually decreases, and the display screen and the vehicle roof could easily pinch the user's hand, posing a safety hazard. Utility Model Content

[0004] This application provides a display device and vehicle to solve the technical problem of safety hazards in the current process of retracting the display screen of a dome screen.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a display device, comprising:

[0007] Base;

[0008] The display screen and the driving assembly are provided, wherein the display screen is connected to the base via the driving assembly; the driving assembly is used to drive the display screen to rotate so that the display screen is in an unfolded state or a retracted state.

[0009] The display screen has a first surface, which faces the base in a retracted state; the touch screen is disposed on the first surface, and the controller is electrically connected to the touch screen and the driving assembly; the controller is used to control the driving assembly to stop working when the touch screen is touched.

[0010] In this way, when the display is retracted, the drive component causes the display to flip. When the user's hand reaches into the angled area between the base and the first surface of the display and comes into contact with the touch area, the controller controls the drive component to stop working, thus preventing the display from pinching the user's hand when it is retracted, eliminating safety hazards, and increasing safety during use.

[0011] In some embodiments, the touch unit is disposed at the edge of the first surface.

[0012] In this way, since the touch unit is located at the edge of the first surface, when the user's hand reaches into the area between the display screen and the base, it will first touch the edge of the first surface, which facilitates the timely response of the touch unit and ensures the user's safe use.

[0013] In some embodiments, the touch unit includes a first touch unit body and a second touch unit body, wherein the first touch unit body and the second touch unit body are respectively disposed on two opposite edges of the first surface.

[0014] In this way, since the free end of the display screen (the end opposite to the hinge between the display screen and the base) is far from the user, the user, especially the child user, will not touch the free end of the display screen when the display screen is retracted. Therefore, setting the first touch unit body and the second touch unit body on the two opposite edges of the first surface can ensure safe use while facilitating the circuit connection of the first touch unit body and the second touch unit body, and increasing the convenience of installation.

[0015] In some embodiments, the touch unit includes a capacitive touch film.

[0016] In this way, when the user's hand touches the area covered by the capacitive touch film, the capacitive touch film will immediately generate a trigger signal. This signal is transmitted directly to the controller through the transmission channel. After receiving the trigger signal, the controller will quickly activate the drive component's pause mechanism, causing the movement of the display screen to stop in a very short time. This design method responds quickly and fundamentally eliminates the risk of pinching fingers caused by the drive component driving the display screen to close or move, significantly improving the safety of the display device.

[0017] In some embodiments, the drive assembly includes a drive element, a drive block, and a connecting rod;

[0018] The driving component is connected to the base, and the driving block is connected to the output end of the driving component. The driving component is used to drive the driving block to move along a first direction, which is parallel to the plane where the display screen is located in the retracted state. One end of the display screen is hinged to the driving block. One end of the connecting rod is hinged to the base, and the other end of the connecting rod is hinged to the display screen. The hinge axis between the display screen and the driving block, the hinge axis between the connecting rod and the base, and the hinge axis between the connecting rod and the display screen are parallel to each other and perpendicular to the first direction.

[0019] In this way, the drive assembly can unfold and retract the display screen through the cooperation of the drive components, drive blocks and connecting rods. The folding structure design reduces space occupation, and the connection between the connecting rod and the display screen is located on the non-display surface of the display screen, avoiding occupying the display surface, increasing the display area of ​​the display screen and improving the user experience.

[0020] In some embodiments, the first surface is provided with a hinge seat, the other end of the connecting rod is hinged to the hinge seat, and the touch portion is disposed on the side of the hinge seat opposite to the first surface.

[0021] In this way, the structural strength at the hinge position can be increased by hinged to the connecting rod. In addition, the hinge can provide a mounting base for the touch unit, increasing the convenience of installation.

[0022] In some embodiments, the hinge seat is provided with a clearance groove, and in the retracted state, at least a portion of the connecting rod is accommodated in the clearance groove.

[0023] In this way, the connecting rod is hinged to the side wall of the clearance groove, reducing the installation space required in the thickness direction of the display screen. In the retracted state, part of the connecting rod is housed in the clearance groove, reducing the space occupied in the retracted state and making the structure of the display device more compact.

[0024] In some embodiments, the touch unit is provided with a clearance opening at a position corresponding to the clearance groove.

[0025] In this way, setting a clearance opening on the touch unit can reduce its own structural area and lower costs, while also providing clearance space for the rotation of the linkage, thus meeting design requirements.

[0026] In some embodiments, the base has a receiving groove on the side facing the display screen, and in the retracted state, the display screen retracts into the receiving groove.

[0027] In this way, when the display is retracted, it returns to the receiving slot, leaving only the second side of the display exposed. This increases the aesthetic appeal and prevents the user from scratching the display during movement, thus avoiding injury to the customer and further enhancing safety.

[0028] Secondly, this application also provides a vehicle, including a body and the aforementioned display device, wherein the body forms a passenger compartment, the display device is disposed on the top of the passenger compartment, and the display device is connected to the body.

[0029] It should be noted that the technical effects brought about by the second aspect of this application can be referred to the technical effects brought about by the corresponding implementation of the first aspect, and will not be repeated here. Attached Figure Description

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0042] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0043] This application provides a vehicle including a body and a display device. The body forms a passenger compartment, and the display device is mounted on the top of the passenger compartment and connected to the body. Specifically, the base 1 of the display device is connected to the roof of the body. The method of connecting the display device to the vehicle body is not limited; for example, the base 1 of the display device can be connected to the roof of the body by bolts or welding, and can be designed according to actual needs.

[0044] There are no restrictions on the type of vehicle; it can be public transportation such as buses and coaches, or private vehicles such as sedans, SUVs (short for Sport Utility Vehicles), and MPVs (short for Multi-Purpose Vehicles). The body type depends on the model, but these are not restrictive. The display device is typically located above the seats. When used in sedans, SUVs, or MPVs, the display device is usually positioned above the rear seats, functioning as a panoramic screen to provide rear passengers with a rich audio-visual experience.

[0045] Combination Figures 1 to 6 As shown, the display device provided in this application embodiment includes a base 1, a display screen 2, a driving component 3, a touch unit 4, and a controller.

[0046] Combination Figure 2 and Figure 4 As shown, the display screen 2 is connected to the base 1 via a drive assembly 3. The base 1 is connected to the vehicle body, and the connection between the base 1 and the vehicle body includes, but is not limited to, bolted connections or welding. The drive assembly 3 is used to drive the display screen 2 to rotate, so that the display screen 2 is in an unfolded or retracted state. Figure 1 and Figure 2 As shown, in the retracted state, the display screen 2 is attached to the base 1. Combined Figure 5 and Figure 6 As shown, in the unfolded state, the plane where the display screen 2 is located forms a certain angle with the plane where the base 1 is located, so that the plane where the display screen 2 is located forms a certain angle with the horizontal plane, or the plane where the display screen 2 is located is perpendicular to the horizontal plane. These are not limiting factors.

[0047] The display screen 2 has a first surface 21, and correspondingly, the display screen 2 also has a second surface 22. The first surface 21 and the second surface 22 are arranged opposite to each other along the thickness direction of the display screen 2. Figure 1 , Figure 2 and Figure 3 As shown, in the retracted state, the first surface 21 faces the base 1, and the second surface 22 faces away from the base 1. The touch unit 4 is disposed on the first surface 21, and the controller is electrically connected to the touch unit 4 and the drive assembly 3. The controller is used to control the drive assembly 3 to stop working when the touch unit 4 is touched. Specifically, after the touch unit 4 is touched by a hand, it sends a working signal. Upon receiving this working signal, the controller issues a stop / shutdown command, and the drive assembly 3 stops operating upon receiving the stop / shutdown command. It is understood that in some embodiments, the drive assembly 3 can also be controlled to rotate in the opposite direction after receiving the stop / shutdown command, to avoid continuous damage to the user's hand caused by being in a clamped state.

[0048] In this way, when the display screen 2 is in the retracted state, the drive component 3 drives the display screen 2 to flip. When the user's hand is inserted into the angled area between the base 1 and the first surface 21 of the display screen 2 and comes into contact with the touch unit 4, the controller controls the drive component 3 to stop working, so as to avoid the display screen 2 pinching the user's hand in the retracted state, eliminate safety hazards, and increase the safety of use.

[0049] In some embodiments, combined with Figure 3 , Figure 5 and Figure 6 As shown, the touch unit 4 is located at the edge of the first surface 21.

[0050] In this way, since the touch unit 4 is located at the edge of the first surface 21, when the user's hand reaches into the area between the display screen 2 and the base 1, it will first touch the edge of the first surface 21, which facilitates the timely response of the touch unit 4 and ensures the user's safe use.

[0051] In some embodiments, combined with Figure 3 and Figure 5As shown, the touch unit 4 includes a first touch unit body 41 and a second touch unit body 42, which are respectively disposed on two opposite edges of the first surface 21. Specifically, one side of the display screen 2 is at least hinged to the base 1, and the first touch unit body 41 and the second touch unit body 42 are spaced apart along the axial direction of the hinge axis of the display screen 2.

[0052] In this way, since the free end of the display screen 2 (the end opposite to the hinge between the display screen 2 and the base 1) is far away from the user, the user, especially the child user, will not touch the free end of the display screen 2 when the display screen 2 is retracted. Therefore, by setting the first touch unit body 41 and the second touch unit body 42 on the two opposite edges of the first surface 21, it is possible to ensure safe use while facilitating the circuit connection of the first touch unit body 41 and the second touch unit body 42, thus increasing the convenience of installation.

[0053] In other embodiments, one side of the display screen 2 is at least hinged to the base 1, and this side of the display screen 2 extends into the interior of the base 1, making it inaccessible to the user. In this case, the touch unit 4 surrounds the other three edges of the first surface 21 of the display screen 2.

[0054] In this way, the touch unit 4 will be triggered no matter which direction the user's hand is inserted into the angled area between the display screen 2 and the base 1, further increasing the safety of the display device.

[0055] In some embodiments, the lengths of the first touch body 41 and the second touch body 42 may be less than the length of the display screen 2, such that the first touch body 41 and the second touch body 42 are close to the side of the display screen 2 away from its free end.

[0056] This allows the first touch unit body 41 and the second touch unit body 42 to be close to the non-free end of the display screen 2, reducing their structural costs.

[0057] In some embodiments, the touch unit 4 includes a capacitive touch film 43.

[0058] The capacitive touch film 43 typically consists of a multi-layer structure, including a protective layer, a touch layer, an insulating layer, a conductive layer, and a base layer. The outermost layer is a glass protective layer or a polyethylene terephthalate protective layer, which serves a protective function; next is the touch layer, which is generally made of indium tin oxide coating and covers the insulating layer; the insulating layer is made of materials such as glass or organic thin film, and is used to isolate the touch layer and the conductive layer; the conductive layer is usually composed of a grid of wires or conductive patterns, and is responsible for collecting touch signals; the bottom layer is the base layer, which is usually a glass layer or a polycarbonate layer, and is used to adhere to the first surface 21 of the display screen 2.

[0059] When a user's finger touches the capacitive touch film 43, a new capacitor is formed between the finger and the touch layer because the human body is a good conductor, changing the original capacitive coupling state. This change is detected by the sensor, amplified by the conversion circuit, and transmitted to the controller. Upon receiving the signal, the controller issues a working command to control the drive component 3 to stop retracting.

[0060] In this way, when the user's hand touches the area covered by the capacitive touch film 43, the capacitive touch film 43 will immediately generate a trigger signal; this signal is transmitted directly to the controller through the transmission channel. After receiving the trigger signal, the controller will quickly activate the pause mechanism of the drive component 3, so that the movement of the display screen 2 stops in a very short time. This design method responds quickly and fundamentally eliminates the risk of pinching fingers caused by the drive component 3 driving the display screen 2 to close or move, significantly improving the safety of the display device.

[0061] In other embodiments, the touch unit 4 includes a resistive touch film.

[0062] Resistive touch films typically employ a structure consisting of a thin film and glass. Both the thin film and the glass are coated with an ITO (indium tin oxide) coating, and the two layers are separated and insulated by uniformly arranged transparent insulating dots.

[0063] When a touch operation is performed, the ITO in the lower layer of the film will come into contact with the ITO in the upper layer of the glass, and the corresponding electrical signal will be transmitted through the sensor. After the signal is converted, it will be sent to the controller. After receiving the signal, the controller will issue a working command to control the drive component 3 to stop the retraction state.

[0064] In this way, when the user's hand touches the resistive touch film, the controller can also respond quickly to control the drive component 3 to stop the action of turning off the display screen 2, increasing the safety of use.

[0065] As can be seen, the design of the touch unit 4 is not restricted and can be designed according to actual needs.

[0066] In related technologies, there are various ways to unfold and retract the display screen 2. For example, in the first method, one side of the display screen 2 is hinged to the base 1, and the display screen 2 retracts or unfolds by rotating around its hinge axis. In this case, the first surface 21 of the display screen 2 is either the display surface or the non-display surface, meaning that when the display screen 2 retracts, its display surface or non-display surface is against the base 1. Another example is the second method, where one side of the display screen 2 is hinged to the base 1, and the display screen 2 also slides against the base 1. When unfolding or retracting, the display screen 2 rotates and slides relative to the base 1. In this case, the first surface 21 of the display screen 2 is the non-display surface, meaning that when the display screen 2 retracts, its non-display surface is against the base 1. The driving methods of the display screen 2 under different design configurations will be explained below:

[0067] In the first embodiment, the driving component 3 includes an electric push rod, one end of which is hinged to the base 1, and the other end of which is hinged to one side of the display surface of the display screen 2. The extension or retraction of the electric push rod enables the display screen 2 to unfold or retract. It is understood that in other embodiments, the driving component 3 includes an electric push rod, one end of which is hinged to the base 1, and the other end of which is hinged to the non-display surface of the display screen 2. The extension or retraction of the electric push rod enables the display screen 2 to unfold or retract. Therefore, the design of the driving component 3 is not limited and can be designed according to actual needs.

[0068] In this way, the structure of the drive component 3 is simple, the operation is convenient, and the structural cost can be reduced.

[0069] In the second approach, combined with Figure 4 and Figure 7 As shown, in some embodiments, the drive assembly 3 includes a drive element 31, a drive block 313, and a connecting rod 32.

[0070] The driving component 31 is connected to the base 1, and the driving block 313 is connected to the output end of the driving component 31. The driving component 31 is used to drive the driving block 313 to move along a first direction, which is parallel to the plane where the display screen 2 is located in the retracted state. One end of the display screen 2 is hinged to the driving block 313; one end of the connecting rod 32 is hinged to the base 1, and the other end of the connecting rod 32 is hinged to the display screen 2, specifically to the first surface 21 (non-display surface) of the display screen 2; the hinge axis between the display screen 2 and the driving block 313, the hinge axis between the connecting rod 32 and the base 1, and the hinge axis between the connecting rod 32 and the display screen 2 are parallel to each other and perpendicular to the first direction.

[0071] When the display screen 2 unfolds, the driving component 31 drives the driving block 313 to move. The driving block 313 will drive one end of the display screen 2 to move along the first direction. At this time, since the end of the driving block 313 is hinged to the end of the display screen 2, and the two ends of the connecting rod 32 are hinged to the base 1 and the display screen 2 respectively, while one end of the display screen 2 is moving, under the support force of the connecting rod 32, the other end of the display screen 2 will move in the direction away from the base 1, so that the display screen 2 flips and unfolds.

[0072] When the display screen 2 retracts, the drive component 31 drives the drive block 313 to move in the opposite direction. The drive block 313 will drive one end of the display screen 2 to move. At this time, under the pulling force of the connecting rod 32, the other end of the display screen 2 will move along the direction of the base 1, so that the display screen 2 retracts.

[0073] In this way, the drive assembly 3 can realize the unfolding and retraction of the display screen 2 through the cooperation of the drive component 31, the drive block 313 and the connecting rod 32. The folding structure design can reduce space occupation, and the connection position of the connecting rod 32 with the display screen 2 is located on the non-display surface of the display screen 2, avoiding occupying the display surface of the display screen 2, increasing the display area of ​​the display screen 2 and improving the user experience.

[0074] In some embodiments, the drive member 31 includes a drive motor 311 and a lead screw 312. The drive motor 311 is connected to the base 1. One end of the lead screw 312 is connected to the drive motor 311, and the other end of the lead screw 312 is rotatably engaged with the base 1. The lead screw 312 extends along a first direction. The drive block 313 is sleeved on the outer periphery of the lead screw 312 and is threadedly engaged with the lead screw 312.

[0075] In this way, by driving the lead screw 312 to rotate through the drive motor 311, the drive block 313 can be moved along the first direction through the lead screw 312, making driving convenient.

[0076] In some embodiments, the first surface 21 is provided with a hinge seat 211, the other end of the connecting rod 32 is hinged to the hinge seat 211, and the touch part 4 is provided on the side of the hinge seat 211 opposite to the first surface 21.

[0077] In this way, the structural strength at the hinge position can be increased by hinged to the connecting rod 32 via the hinge seat 211. In addition, the hinge seat 211 can provide a mounting base for the touch unit 4, increasing the convenience of installing the touch unit 4.

[0078] In some embodiments, the hinge 211 is located near the non-free end of the display screen 2 so that the touch unit 4 is located near the non-free end of the display screen 2, thereby reducing space occupation and simplifying the structure.

[0079] In some embodiments, the hinge seat 211 is provided with a relief groove 2111. The opening of the relief groove 2111 makes the hinge seat 211 have a U-shaped structure. The connecting rod 32 is hinged to the side wall of the relief groove 2111. In the retracted state, at least part of the connecting rod 32 is accommodated in the relief groove 2111.

[0080] In this way, the connecting rod 32 is hinged to the side wall of the clearance groove 2111, reducing the installation space used in the thickness direction of the display screen 2. In the retracted state, part of the connecting rod 32 is accommodated in the clearance groove 2111, reducing the space occupied in the retracted state, making the structure of the display device more compact.

[0081] In some embodiments, the touch unit 4 is provided with a relief opening 431 at a position corresponding to the relief groove 2111. Specifically, the relief opening 431 and the relief groove 2111 are positioned opposite each other along the thickness direction of the display screen 2.

[0082] In this way, setting the clearance opening 431 on the touch unit 4 can reduce its own structural area and reduce costs, and provide clearance space for the rotation of the linkage 32, thus meeting the design requirements.

[0083] In some embodiments, the touch unit 4 further includes a wiring unit 432, the display screen 2 is provided with a circuit board, the wiring unit 432 is electrically connected to the circuit board, and the circuit board is electrically connected to the controller.

[0084] In this way, when the touch unit 4 is touched, it transmits the touch signal to the circuit board, and the circuit board feeds the signal back to the controller, which then issues the corresponding control signal.

[0085] In some embodiments, the wiring portion 432 of the touch unit 4 and the circuit board use a flexible circuit board as the electrical component connection medium to reliably connect the touch unit 4 and the circuit board.

[0086] In some embodiments, the controller here may be the vehicle's control system, which can collect and transmit signals through the vehicle's control system, and then control the drive component 3 to perform corresponding actions based on the signals fed back by the touch unit 4.

[0087] This eliminates the need for an additional controller, resulting in high integration and reduced costs.

[0088] In some embodiments, the base 1 has a receiving groove on the side facing the display screen 2, and in the retracted state, the display screen 2 retracts into the receiving groove.

[0089] Specifically, such as Figure 3 As shown, a frame 11 is provided on the side of the base 1 facing the display screen 2. The frame 11 and the base 1 form a receiving groove, and the shape of the receiving groove matches the shape of the display screen 2, which facilitates the storage of the display screen 2.

[0090] In this way, when the display screen 2 is in the retracted state, it retracts into the receiving slot, leaving only the second side 22 of the display screen 2 exposed, which increases the aesthetics and prevents the user from scratching the display screen 2 when moving, thus avoiding injury to the customer and further increasing the safety of use.

[0091] In some embodiments, the display device of this application can be used as a panoramic sunroof screen for vehicles. It is understood that the display device can also be applied in other scenarios where the display screen 2 needs to be extended or retracted, and these are not limiting.

[0092] This application combines touch sensing technology with motion mechanism safety control. By monitoring the triggered contact status of the touch unit 4 in the display screen 2 in real time, it controls the driving state of the drive component 3, achieving an intelligent anti-pinch effect and providing users with a safe and reliable user experience. Furthermore, the touch unit 4 uses a capacitive touch film 43, which serves as the core sensing element and can accurately capture surface touch signals. When it detects that a user's limb is touching the angled area between the display screen 2 and the base 1, it can achieve a millisecond-level response, resulting in fast response speed and significantly improving the safety of the vehicle-mounted panoramic sunroof screen.

[0093] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0094] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
