Description

Technical Field

[0001] The present application relates to the field of vehicle manufacturing technology, and in particular to a display screen assembly and a vehicle. Background Art

[0002] With the improvement of people's living standards, the electrification of automobiles and the rapid development of electric vehicles, people's requirements for automobiles are no longer simply a means of transportation, but have higher expectations for the vehicle's beauty, comfort, safety, environmental protection, large space, convenience, scalability, entertainment and other dimensions.

[0003] The central control screen is a display installed inside the vehicle body that centrally displays information, provides a human-machine interface, and controls related functions. It not only replaces the traditional instrument cluster to provide basic information such as vehicle speed, oil temperature, mileage, and navigation information, but also serves as a multimedia entertainment platform. However, in related technologies, the central control screen is fixed to the center of the dashboard, resulting in poor viewing angles for the driver and front passenger, which in turn affects the user experience. Summary of the Invention

[0004] In view of this, the present application provides a display screen assembly, which includes a display screen and a swing mechanism, thereby enabling the display screen to move in the width direction of the vehicle body, which can effectively improve the user experience. In addition, the present application also provides a vehicle including the above-mentioned display screen assembly.

[0005] In a first aspect, the present application provides a display screen assembly, comprising a display screen and a swing mechanism;

[0006] The swing mechanism includes a first mounting seat, a second mounting seat and a first swing arm; both ends of the first swing arm are rotatably connected to the first mounting seat and the second mounting seat respectively;

[0007] The display screen is movably disposed on the second mounting base, and the display screen can move relative to the second mounting base along a first direction; the first direction is perpendicular to the extension direction of the swing center line of the first swing arm.

[0008] When the display screen assembly of the present application is installed within the cabin, the display screen assembly is adjusted in its mounting position and angle so that the extension direction of the swing centerline of the first swing arm and the first direction are both parallel to a first plane, and the first plane is parallel to both the length and height of the vehicle body.

[0063] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0064] The present application provides a vehicle. The vehicle includes, but is not limited to, a new energy vehicle, a fuel vehicle, a hybrid vehicle, and includes, but is not limited to, a family car, a public bus, and the like.

[0065] The vehicle includes a body and an instrument panel assembly.

[0066] The body is the main structural part of a vehicle, primarily responsible for accommodating passengers and cargo, and covering and protecting the vehicle's mechanical components (such as the engine and chassis). It provides overall rigidity to the vehicle through a frame structure or load-bearing structure. Furthermore, the body has a cabin inside, which can be a cockpit or a combination of a cockpit and a passenger compartment. The following description uses the example of a cabin consisting of both a cockpit and a passenger compartment.

[0067] The instrument panel assembly is located inside the vehicle body, specifically within the cabin, and is located directly in front of the driver and front passenger.

[0068] The instrument panel assembly includes a fixed beam and a display screen assembly.

[0069] The fixed beam is the supporting structure of the instrument panel assembly and is fixedly connected to the vehicle body. The connection between the fixed beam and the vehicle body can be a non-detachable connection such as welding or riveting, or a detachable connection such as bolting.

[0070] In a specific implementation, the fixed beam may be a cross beam extending along the width direction of the vehicle body; or, the fixed beam may be a supporting structure composed of a plurality of beams that are staggered and connected.

[0071] like Figure 1-Figure 3 As shown, the display screen assembly includes a display screen 18 and a swing mechanism.

[0072] The display screen 18 may be a screen that integrates instrument display and entertainment functions. Alternatively, it may be a screen that only has entertainment functions. The instrument display includes, but is not limited to, vehicle speed, tachometer, and water temperature; and the entertainment functions include, but are not limited to, audio and video entertainment and gaming entertainment.

[0073] like Figures 1-4 As shown, the swing mechanism includes a first mounting base 1, a second mounting base 4 and a first swing arm 2. In addition, both ends of the first swing arm 2 are rotatably connected to the first mounting base 1 and the second mounting base 4 respectively.

[0074] The first mounting base 1 may be an independent component, or the first mounting base 1 may also be a part of a fixed beam or a vehicle body. The following description will be made by taking the first mounting base 1 as an independent component as an example.

[0075] When the first mounting seat 1 is an independent component, it can be fixedly connected to the fixing beam to be fixed inside the vehicle body through the fixing beam, or it can also be directly connected to the vehicle body.

[0076] In some embodiments, as Figure 5 and Figure 6 As shown, the first mounting seat 1 can be a plate-shaped structural member.

[0077] The plate-like structural member has a mounting surface and a connection surface, wherein the mounting surface is a surface of the plate-like structural member used for rotatably connecting to the first swing arm 2. The connection surface is used for connecting to the vehicle body and / or the fixed beam.

[0078] In a further preferred embodiment, Figure 7 and Figure 8 As shown, the first mounting seat 1 includes a mounting plate 101 and a first connecting plate 102 .

[0079] The mounting plate 101 is used to connect other components in the swing mechanism, such as the first swing arm 2 .

[0080] The first connecting plate 102 is fixedly connected to the mounting plate 101 , or the first connecting plate 102 and the mounting plate 101 are integrated, and are used to connect the fixed beam and / or the vehicle body.

[0081] Continue as in Figure 7 and Figure 8 As shown, the mounting plate 101 and the first connecting plate 102 are arranged at an angle. This arrangement makes the mounting surface of the mounting plate 101 and the connecting surface of the first connecting plate 102 non-coplanar. In this way, interference between the connecting structure connected to the first connecting plate 102 (the connecting structure includes but is not limited to a connecting bracket, bolts, etc.) and other components in the swing mechanism (such as the first swing arm 2) can be avoided.

[0082] Furthermore, ribs 103 are provided between the mounting plate 101 and the first connecting plate 102; this effectively improves the connection strength between the mounting plate 101 and the first connecting plate 102, thereby increasing the overall structural strength of the first mounting base 1. The number of ribs 103 provided can be adaptively designed as needed and is not specifically limited in this application. For example, one, two, or even more ribs 103 may be provided between the mounting plate 101 and each first connecting plate 102.

[0083] The number of first connecting plates 102 can be adaptively designed as needed, and this application does not impose specific restrictions on this. In some embodiments, only one first connecting plate 102 can be provided, and the first connecting plate 102 is preferably provided in the middle of the length of the mounting plate 101, so as to improve the uniformity of the support provided by the first connecting plate 102 to the mounting plate 101. In some embodiments, multiple first connecting plates 102 can also be provided (for example, two, three, or even more). In this arrangement, multiple first connecting plates 102 are spaced apart along the length of the mounting plate 101, which can effectively improve the stability of the motion assembly.

[0084] Furthermore, when there are multiple first connecting plates 102, the multiple first connecting plates 102 can be distributed on both sides of the mounting plate 101 along the thickness direction. This arrangement is conducive to stress dispersion, thereby further improving the stability of the first connecting plates 102 supporting the mounting plate 101.

[0085] The second mounting seat 4 includes a connecting portion 401 and a mounting portion 402 .

[0086] The connecting portion 401 and the mounting portion 402 may be two independent components connected to each other, or the connecting portion 401 and the mounting portion 402 may be an integral part.

[0087] The connecting portion 401 is a portion of the second mounting base 4 used to connect to the first swing arm 2. Figures 9-12 As shown, in a specific implementation, there is a protruding columnar structure on the connecting portion 401. During the assembly process, the first swing arm 2 is connected to the columnar structure through a bearing and other structures, thereby realizing the rotational connection between the first swing arm 2 and the second mounting seat 4.

[0088] The mounting portion 402 is the portion of the second mounting base 4 used to connect to the display screen 18. The specific structure of the mounting portion 402 can be adaptively designed according to the connection method between the second mounting base 4 and the display screen 18, and this application does not make any specific restrictions on this.

[0089] Furthermore, the display screen 18 is movably disposed on the second mounting base 4 , and the display screen 18 can move relative to the second mounting base 4 along a first direction, which is perpendicular to the extension direction of the swing center line of the first swing arm 2 .

[0090] The extending direction of the swing centerline of the first swing arm 2 refers to the rotation centerline of the first swing arm 2 relative to the first mounting base 1. For example, when the first swing arm 2 is rotationally connected to the first mounting base 1 through the first shaft 13, the swing centerline is the axis of the first shaft 13.

[0091] The display screen 18 and the second mounting base 4 can be slidably connected; or, the display screen 18 and the second mounting base 4 can also be detachably connected, and in the first direction, the second mounting base 4 is provided with a plurality of connection points that are detachably connected to the display screen 18, and the display screen 18 can be moved relative to the second mounting base 4 in the first direction by connecting the display screen 18 to different connection points.

[0092] When the display screen assembly of this embodiment is assembled within the cabin, the display screen assembly's mounting position and angle are adjusted so that the extension direction of the swing centerline of the first swing arm 2 and the first direction are both parallel to a first plane, which is parallel to both the longitudinal and height directions of the vehicle body. This allows the display screen 18, driven by the first swing arm 2, to move in the width direction of the vehicle body. Furthermore, when the display screen 18 moves in the first direction relative to the second mounting base 4, the display screen 18 can also move in the height direction of the vehicle body.

[0093] In this way, during normal driving of the vehicle, taking into account driving safety and the entertainment needs of the front passenger, by controlling the first swing arm 2 to rotate relative to the first mounting seat 1, and controlling the display screen 18 to move along the first direction relative to the second mounting seat 4, the display screen 18 can be moved directly in front of the front passenger, so as to facilitate the front passenger to watch videos or play games through the display screen 18; at the same time, since this position is far away from the driver, it can minimize interference with the driver, thereby ensuring driving safety.

[0094] When the vehicle is parked, by controlling the first swing arm 2 to rotate relative to the first mounting base 1 and controlling the display screen 18 to move along the first direction relative to the second mounting base 4, the display screen 18 can be moved to the middle position in the vehicle width direction, so that the driver and the front passenger can entertain themselves together through the display screen 18.

[0095] When the vehicle is parked and only the driver has entertainment needs, the display screen 18 can be moved directly in front of the driver by controlling the first swing arm 2 to rotate relative to the first mounting base 1 and controlling the display screen 18 to move along the first direction relative to the second mounting base 4. Compared with the display screen 18 being in the above-mentioned middle position, the display screen 18 being directly in front of the driver facilitates the interaction between the driver and the display screen 18, thereby improving the driver's entertainment experience.

[0096] In some embodiments, the swing mechanism further includes a second swing arm 3, both ends of which are rotatably connected to the first mounting base 1 and the second mounting base 4. Figure 9 and Figure 12 As shown, the second mounting base 4 has a first connecting structure 4011 and a second connecting structure 4012, and the first connecting structure 4011 and the second connecting structure 4012 are spaced apart along the second direction. The first connecting structure 4011 is used for rotationally connecting to the first swing arm 2, and the second connecting structure 4012 is used for rotationally connecting to the second swing arm 3. The first direction is perpendicular to the second direction.

[0097] With this setup, the display screen 18 can always remain parallel to the vehicle body floor when the swing mechanism is used to adjust its position. This eliminates the need for further rotation of the display screen 18 after the swing mechanism has adjusted its position, making it easier to operate while moving the display screen 18, further enhancing the user experience.

[0098] The first connection structure 4011 and the second connection structure 4012 may be the same or different.

[0099] For example, Figures 9-12 As shown, the first connection structure 4011 and the second connection structure 4012 are both protruding columnar structures.

[0100] like Figure 18 and Figure 20 As shown, one end of the first swing arm 2 connected to the second mounting seat 4, and one end of the second swing arm 3 connected to the second mounting seat 4 are both provided with mounting holes, and the mounting holes are connected to the columnar structure through bearings, thereby realizing the rotational connection between the first swing arm 2 and the second mounting seat 4, and the rotational connection between the second swing arm 3 and the second mounting seat 4.

[0101] In some embodiments, the display screen 18 is slidably connected to the second mounting base 4 via a sliding mechanism.

[0102] The sliding mechanism includes a slide rail 5 and a slide groove 6. The slide rail 5 extends along a first direction, and the slide groove 6 is in sliding cooperation with the slide rail 5.

[0103] The sliding mechanism can be provided with only one group or multiple groups. During implementation, adaptive design can be carried out according to needs.

[0104] In some embodiments, as Figure 1 ,like Figures 9-14 As shown, the slide rail 5 is arranged on the display screen 18 , and the slide groove 6 is arranged on the second mounting seat 4 .

[0105] In this embodiment, the slide rail 5 can be part of the housing of the display screen 18, that is, the slide rail 5 and the housing of the display screen 18 can be an integral part. Alternatively, the slide rail 5 can also be an independent component, in which case the slide rail 5 and the display screen can be connected by a connecting structure such as screws or buckles.

[0106] The chute 6 can be a groove formed on the second mounting seat 4. Alternatively, the chute 6 can also be a groove formed on a slider, and the slider is fixedly connected to the second mounting seat 4.

[0107] In other embodiments, the slide rail 5 is disposed on the second mounting base 4 , and the slide groove 6 is disposed on the display screen 18 .

[0108] In this embodiment, the slide rail 5 can be a protruding structure on the second mounting seat 4, that is, the slide rail 5 and the second mounting seat 4 are an integral part. Alternatively, the slide rail 5 can also be an independent component and fixedly connected to the second mounting seat 4.

[0109] The chute 6 can be a groove formed on the housing of the display screen 18. Or the chute 6 can also be a groove formed on a slider, and the slider is fixedly connected to the display screen 18.

[0110] When the display screen 18 needs to be moved relative to the second mounting base 4, the cooperation between the slide groove 6 and the slide rail 5 can accurately limit the movement direction of the display screen 18, so that it moves only in the first direction. In this way, the movement direction of the display screen 18 can be accurately controlled, thereby facilitating the adjustment of the position of the display screen 18.

[0111] Based on the above-mentioned slide rail 5 structure, in a further preferred embodiment, the display screen assembly also includes a limiting structure, which is used to limit the movement of the display screen 18 relative to the second mounting base 4 in a direction perpendicular to the second plane, and the second plane is parallel to the first direction and the second direction.

[0112] In this way, with the further limiting effect of the limiting structure, the display screen 18 can only move along the first direction relative to the second mounting base 4. This design further strengthens the control of the moving direction of the display screen 18, thereby effectively improving the stability and positioning accuracy of the display screen 18 during movement.

[0113] In some embodiments, as Figure 9 、 Figure 10 and Figure 15 The limiting structure includes a limiting protrusion 7 and a limiting groove 8.

[0114] The limiting protrusion 7 is a protrusion structure extending along the first direction and protruding along the second direction. The limiting groove 8 is a groove extending along the first direction and recessed along the second direction.

[0115] The limiting groove 8 is slidably connected to the limiting protrusion 7, and one of the limiting protrusion 7 and the limiting groove 8 is provided on the second mounting base 4, and the other is provided on the display screen 18. In this way, the display screen 18 is restricted from moving relative to the second mounting base 4 in a direction perpendicular to the second plane without affecting the movement of the display screen 18 relative to the second mounting base 4 in the first direction.

[0116] For example, one of the sidewalls of the slide rail 5 and the sidewall of the slide slot 6 has a limiting protrusion 7, and the other has a limiting groove 8. In other words, the limiting structure is formed in the sliding mechanism. In this arrangement, the limiting structure and the sliding mechanism are integrated into one, thereby simplifying the structure of the display assembly and reducing equipment costs.

[0117] Furthermore, the limiting structures may be provided in only one group or in multiple groups.

[0118] Moreover, when there are multiple groups of limiting structures, in the second direction, the limiting protrusions 7 in the multiple groups of limiting structures can all be set on one side wall of the slide groove 6 (or the slide rail 5), or they can also be distributed on two opposite side walls of the slide groove 6 (or the slide rail 5); the limiting groove 8 is set corresponding to the limiting protrusion 7, and this application will not go into details here.

[0119] In some embodiments, the display screen assembly includes a first drive assembly. This first drive assembly is used to drive the display screen 18 to move relative to the second mounting base 4. Compared to manually driving the display screen 18 to move relative to the second mounting base 4, using the first drive assembly to drive the display screen 18 to move relative to the second mounting base 4 facilitates automated movement of the display screen 18, thereby further improving the user experience.

[0120] In some embodiments, the first drive assembly includes a first drive member 9 .

[0121] The first driving member 9 is disposed on one of the display screen 18 and the second mounting base 4 through a connecting structure, and an output end of the first driving member 9 is connected to the other and can reciprocate along a first direction.

[0122] To control the display screen 18 to move in the first direction relative to the second mounting base 4, it is sufficient to activate the first driving member 9 and move the output end of the first driving member 9 in the first direction. In this arrangement, the first driving member 9 is directly connected between the display screen 18 and the second mounting base 4. Since no transmission structure is required, the structure of the display screen assembly can be simplified and the cost can be reduced.

[0123] In this embodiment, the first driving member 9 can be a hydraulic cylinder or an electric push rod, etc. Of course, this is not a limitation of the present application. In a specific implementation, the first driving member 9 can also be a linear motor or a cylinder, etc.

[0124] In other embodiments, Figure 13 and Figure 14 As shown, the first drive assembly includes a first drive member 9 and a transmission mechanism 10 .

[0125] The first driving member 9 can be arranged on the display screen 18 or on the second mounting base 4 .

[0126] The transmission mechanism 10 is connected between the display screen 18 and the second mounting base 4 and is connected to the first driving member 9. Moreover, under the drive of the first driving member 9, the transmission mechanism 10 can drive the display screen 18 to move relative to the second mounting base 4 along the first direction.

[0127] Compared with the first driving member 9 in the previous embodiment that directly drives the display screen 18 to move relative to the second mounting base 4, in this embodiment, by adding a transmission mechanism 10, the freedom of design of the first driving member 9 can be increased, which is conducive to the reasonable selection of the first driving member 9 (that is, the first driving member 9 in this embodiment is no longer limited to a driving member that causes the driven member to move in a straight line. For example, in addition to selecting the hydraulic cylinder in the previous embodiment as the first driving member 9, a motor can also be selected as the first driving member 9) and reasonable arrangement (the reasonable arrangement includes but is not limited to the setting position of the first driving member 9).

[0128] The transmission mechanism 10 can be a chain transmission mechanism or a gear transmission mechanism, etc., and can be adaptively designed according to needs during implementation.

[0129] like Figure 13 、 Figure 14 、 Figure 16 and Figure 17 As shown, the transmission mechanism 10 includes a chain 1003, a first sprocket 1001 and a second sprocket 1002. The first sprocket 1001 and the second sprocket 1002 are distributed along a first direction and are spaced apart.

[0130] The first sprocket 1001 and the second sprocket 1002 can both be mounted on the second mounting base 4; alternatively, the first sprocket 1001 and the second sprocket 1002 can both be mounted on the display screen 18. Preferably, the first sprocket 1001 and the second sprocket 1002 are both mounted on a structure that is larger in the first direction. This allows for a greater distance between the first sprocket 1001 and the second sprocket 1002, thereby increasing the amount of movement of the display screen 18 relative to the second mounting base 4 in the first direction. The following description will take the example of both the first sprocket 1001 and the second sprocket 1002 being mounted on the display screen 18.

[0131] The chain 1003 is connected between the first sprocket 1001 and the second sprocket 1002 and is used to realize the transmission connection between the first sprocket 1001 and the second sprocket 1002 .

[0132] The chain 1003 includes a first side and a second side that are relatively distributed, wherein the first side is a side of the chain 1003 close to the second mounting seat 4 , and the second side is a side of the chain 1003 close to the display screen 18 .

[0133] like Figure 17 As shown, a connecting member 1004 is provided on the chain 1003. Moreover, the connecting member 1004 is provided on a first side of the chain 1003 and can be connected to the second mounting seat 4.

[0134] The connecting member 1004 may be a sheet metal part, or may be a connecting seat formed by casting or material removal processing.

[0135] Illustratively, the connecting member 1004 includes a third connecting plate and a fourth connecting plate.

[0136] The third connecting plate has two connecting holes, which are used to connect to two adjacent chain pins of the chain 1003. With this arrangement, there is no need to provide a structure on the chain 1003 specifically for connecting the connecting member 1004, which helps to simplify the structure of the chain 1003 and reduce costs and manufacturing difficulty.

[0137] The fourth connecting plate is fixedly connected to the third connecting plate, or is an integral part with the third connecting plate.

[0138] The fourth connecting plate has a connecting surface that can abut against the surface of the second mounting seat 4, so that the fourth connecting plate and the second mounting seat 4 can be connected by welding, threaded connection and / or riveting.

[0139] Furthermore, an angle is formed between the fourth connecting plate and the third connecting plate (the angle includes but is not limited to 90 degrees), and in the second direction, the fourth connecting plate extends away from the chain 1003. This facilitates connecting the chain 1003 to the second mounting base 4 using the connecting member 1004.

[0140] like Figure 13 and Figure 14 As shown, in some embodiments, the first sprocket 1001 and the second sprocket 1002 are both rotatably disposed on the surface of the display screen 18 facing the second mounting base 4. Furthermore, the directions in which the rotational centerlines of the first sprocket 1001 and the second sprocket 1002 extend are both perpendicular to the first direction. This ensures that the chain 1003 can drive the display screen 18 to move relative to the second mounting base 4 in the first direction.

[0141] Based on the above-mentioned first sprocket 1001 and second sprocket 1002, in some embodiments, the first driving member 9 can be connected to the first sprocket 1001 to achieve the connection between the first driving member 9 and the chain 1003 transmission mechanism 10. In this case, the first sprocket 1001 is a driving sprocket. Driven by the first driving member 9, the first sprocket 1001 can rotate around its axis and drive the second sprocket 1002 to rotate synchronously.

[0142] The connection method between the first sprocket 1001 and the first driving member 9 can be adaptively designed according to the first driving member 9. For example, when the first driving member 9 is a motor, a connection structure (including but not limited to a spline structure) can be used to coaxially connect the output shaft of the first driving member 9 and the first sprocket 1001. When the first driving member 9 is a hydraulic cylinder, a structure such as a gear and a rack can be used to connect the first driving member 9 and the first sprocket 1001.

[0143] In other embodiments, the first driving member 9 can be connected to the second sprocket 1002 to achieve the connection between the first driving member 9 and the chain 1003 transmission mechanism 10. In this case, the second sprocket 1002 is a driving sprocket. Under the drive of the first driving member 9, the second sprocket 1002 can rotate around its axis and drive the first sprocket 1001 to rotate synchronously.

[0144] The connection method between the second sprocket 1002 and the first driving member 9 can refer to the connection method between the first sprocket 1001 and the first driving member 9 in the previous embodiment, and will not be repeated in this application.

[0145] In other embodiments, the first driving member 9 may also be connected to the first sprocket 1001 and the second sprocket 1002 at the same time to achieve the connection between the first driving member 9 and the chain 1003 transmission mechanism 10.

[0146] At this time, a transmission structure such as a gear set can be used to connect the first driving member 9 to the two sprockets. Alternatively, two first driving members 9 can be provided, and the two first driving members 9 are respectively connected to the first sprocket 1001 and the second sprocket 1002, and can drive the first sprocket 1001 and the second sprocket 1002 to rotate synchronously.

[0147] In some embodiments, the first sprocket 1001 and the second sprocket 1002 each include a sprocket body and a sprocket shaft.

[0148] A plurality of sprocket teeth are evenly arranged on the circumferential surface of the sprocket body and can be meshed and connected with the chain 1003 .

[0149] In the second direction, the sprocket shaft protrudes from the end surfaces on opposite sides of the sprocket body, and the axis of the sprocket shaft coincides with the rotation center line of the sprocket body.

[0150] The sprocket shaft and the sprocket body may be two components connected to each other, or the sprocket shaft and the sprocket body may be an integral part.

[0151] In some embodiments, the first sprocket 1001 and the second sprocket 1002 are rotatably connected to the display screen 18 in the same manner.

[0152] For example, Figure 11As shown, the display screen assembly further includes a rotating bracket 11. The first sprocket 1001 and the second sprocket 1002 can be rotatably connected to the rotating bracket 11 via a sprocket shaft, thereby enabling the first sprocket 1001 and the second sprocket 1002 to be rotatably disposed on the display screen 18.

[0153] The rotating bracket 11 can be a separate component and can be connected to the surface of the display screen 18 facing the second mounting base 4 via a connection structure such as a threaded structure. Alternatively, the rotating bracket 11 can be a protrusion on the surface of the display screen 18 facing the second mounting base, that is, the rotating bracket 11 and the housing of the display screen 18 are integral. The following description uses the rotating bracket 11 as an example of a separate component.

[0154] like Figure 16 As shown, the rotating bracket 11 includes a first bracket body 1101 and a second bracket body 1102 .

[0155] The shape of the first bracket body 1101 and the shape of the second bracket body 1102 can be the same or different, which is not a limitation of the present application. However, both the first bracket body 1101 and the second bracket body 1102 need to be arranged on the surface of the side of the display screen 18 facing the second mounting seat 4.

[0156] In addition, the first bracket body 1101 and the second bracket body 1102 can be two independent components. Alternatively, the first bracket body 1101 and the second bracket body 1102 can also be an integrated part. In this case, the rotating bracket 11 further includes a base body, which is used to connect the first bracket body 1101 and the second bracket body 1102.

[0157] like Figure 16 As shown, the first bracket body 1101 and the second bracket body 1102 are spaced apart in the second direction. The spacing between the first bracket body 1101 and the second bracket body 1102 can be designed according to the size of the sprocket body in the second direction during implementation, and should at least ensure that the sprocket body can be rotatably disposed between the first bracket body 1101 and the second bracket body 1102.

[0158] Both the first bracket body 1101 and the second bracket body 1102 are provided with mounting holes, and in the second direction, the mounting hole of the first bracket body 1101 is arranged opposite to the mounting hole of the second bracket body 1102 to ensure that the sprocket shaft can be rotatably connected to the mounting hole of the first bracket body 1101 and the mounting hole of the second bracket body 1102 at the same time.

[0159] The rotational connection between the first bracket body 1101 and the sprocket shaft, and between the second bracket body 1102 and the sprocket shaft, can be achieved through the clearance fit between the mounting hole and the sprocket shaft, or a bearing can be arranged in the mounting hole to achieve the connection between the sprocket shaft and the bracket body (including the first bracket body 1101 and the second bracket body 1102) through the bearing.

[0160] In this embodiment, in the second direction, the first bracket body 1101 and the second bracket body 1102 are located on opposite sides of the sprocket body. The sprocket body is rotationally connected to the first bracket body 1101 and the second bracket body 1102 via the sprocket shaft. Thus, the sprocket is rotationally constrained to the display screen 18 on both sides of the sprocket in the second direction through the rotatable brackets. This design effectively improves the stability of the sprocket when rotating relative to the display screen 18.

[0161] In some embodiments, the first sprocket 1001 and the second sprocket 1002 are rotatably connected to the display screen 18 in different ways.

[0162] Exemplarily, the first driving member 9 is a sprocket drive motor.

[0163] The first sprocket 1001 is rotatably connected to the display screen 18 via the rotating bracket 11 . For details, reference may be made to the rotatably connected manner of the first sprocket 1001 and the display screen 18 in the previous embodiment, which will not be described in detail in this application.

[0164] The second sprocket 1002 is fixed to the output shaft of the sprocket drive motor and is rotationally connected to the display screen 18 through the sprocket drive motor.

[0165] In this embodiment, the second sprocket 1002 is rotatably connected to the display screen 18 via a sprocket drive motor. Since there is no need to set up a rotating bracket 11 to connect the second sprocket 1002 and the display screen 18, the structure of the display screen assembly can be simplified and the cost can be reduced.

[0166] In some embodiments, the display screen assembly further includes a second drive component, which is disposed on the first mounting base 1 and connected to the first swing arm 2 and / or the second swing arm 3 .

[0167] With this setup, when the swing mechanism is needed to adjust the position of display screen 18, simply activate the second drive assembly and wait for display screen 18 to reach the target position before stopping. Compared to manual adjustment, using the second drive assembly to drive first swing arm 2 and / or second swing arm 3 allows for more efficient automation of display screen 18 position adjustment. This not only streamlines the operational process but also significantly enhances the user experience.

[0168] Exemplarily, the second driving assembly is connected to the first swing arm 2 or the second swing arm 3. In this arrangement, one of the first swing arm 2 and the second swing arm 3 is the active arm, and the other is the driven arm.

[0169] Further preferably, the second driving assembly can simultaneously drive the first swing arm 2 and the second swing arm 3 to rotate.

[0170] In an exemplary embodiment, the second driving assembly is mounted on the first mounting seat 1 , and the second driving assembly includes a second driving member 12 and a transmission structure.

[0171] The second driving member 12 may be a motor, or the second driving member 12 may be a hydraulic cylinder, etc.

[0172] The second driving member 12 is connected to the first swing arm 2 and can drive the first swing arm 2 to rotate.

[0173] The connection method between the second driving member 12 and the first swing arm 2 needs to be adaptively designed based on the type of second driving member 12. For example, the first swing arm 2 is rotatably connected to the first mounting base 1 via a first shaft 13. When the second driving member 12 is a motor, the motor's output shaft can be coaxially connected to the first shaft 13 using a connector 1004. Alternatively, the motor's output shaft and the first shaft 13 can be connected via a gear train. When the second driving member 12 is a hydraulic cylinder, a gear, rack, or similar device can be used to connect the hydraulic cylinder's telescopic end to the first shaft 13.

[0174] The transmission structure is connected between the first swing arm 2 and the second swing arm 3; in a specific implementation, the transmission structure can be a chain transmission structure, or the transmission structure can also be a belt transmission structure, or the transmission structure can also be a gear transmission structure.

[0175] In this arrangement, the driving force of the second driving member 12 can be transmitted to the second swing arm 3 through the transmission structure, so that the first swing arm 2 and the second swing arm 3 are both power arms. This can prevent the display screen 18 from shaking or even becoming immobile during movement due to insufficient driving force from the first swing arm 2 or the second swing arm 3.

[0176] Specifically, as described above, the display screen 18 is connected to the first and second swing arms 2 and 3 via the second mounting base 4. In other words, the first and second swing arms 2 and 3 both serve as support arms for the display screen 18. During the movement of the display screen 18, both the first and second swing arms 2 and 3 must overcome the gravity of the display screen 18 to perform work. Based on this, if only one of the first and second swing arms 2 and 3 is connected to the second driving member 12, the other acts as a driven arm, rotating under the drive of the first swing arm 2. For ease of description, the swing arm connected to the second driving member 12 will be referred to as the active arm. It can be understood that under this setting, the active arm transmits force to the driven arm through the second mounting base 4. During the movement of the display screen 18, the force transmitted from the active arm to the driven arm through the second mounting base 4 (for the convenience of description, this force will be referred to as the first force below) is affected by the angle between the active arm and the second mounting base 4 and the angle between the driven arm and the second mounting base 4. Moreover, when the display screen 18 moves to a certain position, the component of the first force in the opposite direction of gravity is particularly small, resulting in that the component is insufficient to support the display screen 18, which in turn causes the display screen 18 to shake or even be unable to continue moving.

[0177] In this embodiment, since the first swing arm 2 and the second swing arm 3 are both power arms, the force they can apply to the display screen 18 to overcome its gravity and do work is not affected by the angle between the swing arm (including the first swing arm 2 and the second swing arm 3) and the second mounting base 4, thereby avoiding the above-mentioned shaking of the display screen 18 or even the inability to continue moving caused by insufficient supporting force of the driven arm on the display screen 18.

[0178] In an exemplary embodiment, the second driving assembly is mounted on the first mounting seat 1 , and the second driving assembly includes a second driving member 12 and a third driving member.

[0179] The second driving member 12 is connected to the first swing arm 2 and is used to drive the first swing arm 2 to rotate.

[0180] The third driving member is connected to the second swing arm 3 and is used to drive the second swing arm 3 to rotate.

[0181] The specific configuration of the second driving member 12 and the third driving member can refer to the second driving member 12 in the previous embodiment, and will not be repeated in this application.

[0182] Furthermore, in a specific implementation, the second drive member 12 and the third drive member may have the same drive structure. For example, the second drive member 12 and the third drive member may both be motors. Alternatively, the second drive member 12 and the third drive member may have different drive structures. For example, one of the second drive member 12 and the third drive member may be a motor and the other may be a hydraulic cylinder. Regardless of whether the second drive member 12 and the third drive member have the same drive structure, it is necessary to ensure that the rotational speed of the first swing arm 2 driven by the second drive member 12 is equal to the rotational speed of the second swing arm 3 driven by the third drive member.

[0183] Similar to the previous embodiment, the first swing arm 2 and the second swing arm 3 in this embodiment are also power arms. The force they can apply to the display screen 18 to overcome its gravity and do work is not affected by the angle between the swing arm (including the first swing arm 2 and the second swing arm 3) and the second mounting base 4, thereby avoiding the shaking of the display screen 18 or even the inability to continue moving caused by the insufficient supporting force of the driven arm on the display screen 18.

[0184] In some embodiments, as Figure 5 and Figure 6 As shown, the second drive assembly includes a swing arm drive motor, which is fixedly mounted on the first mounting base 1. The first swing arm 2 is rotatably mounted on the first mounting base 1 via the swing arm drive motor. As a result, there is no need for an additional structure for rotational connection between the first mounting base 1 and the first swing arm 2, thereby simplifying the structure of the display assembly and reducing equipment costs.

[0185] For example, Figure 5 and Figure 6 As shown, the swing arm drive motor has a second connecting plate 1201 , which is used to fix the swing arm drive motor to the first mounting seat 1 .

[0186] like Figure 18 As shown, a first connecting groove 201 is provided at one end of the first swing arm 2 connected to the first shaft 13. The bottom of this first connecting groove 201 has a first connecting hole 202, and the end surface of the first connecting groove 201 is elliptical. A connecting block 1202 is fixed to the output end of the swing arm drive motor. The shape of this connecting block 1202 is consistent with that of the first connecting groove 201, and a first threaded hole 1203 is provided on the end surface of the connecting block 1202 at the position corresponding to the first connecting hole 202.

[0187] When assembling the first swing arm 2 to the swing arm drive motor, first assemble the connecting block 1202 into the first connecting groove 201 , then control the screw to pass through the first connecting hole 202 from the side away from the swing arm drive motor and screw into the first threaded hole 1203 on the connecting block 1202 .

[0188] In this configuration, screws are used to engage the first connecting groove 201 and the connecting block 1202 to limit the swing arm drive motor and the first swing arm 2 in the axial direction of the motor output shaft. Compared to the technical solution of the related art that uses an interference fit for limiting, the configuration in this embodiment makes it easier to assemble the swing arm drive motor and the first swing arm 2. In addition, because the end face of the first connecting groove 201 is elliptical and the connecting block 1202 is adapted to the shape of the first connecting groove 201, after the swing arm drive motor is connected to the first swing arm 2, the first connecting groove 201 and the connecting block 1202 can limit the rotation of the first swing arm 2 relative to the motor output shaft, thereby avoiding the use of additional limiting structures and helping to simplify the structure.

[0189] Of course, the shape of the end face of the first connecting groove 201 can be adaptively adjusted according to needs during specific implementation. For example, the shape of the end face of the first connecting groove 201 can also be set to be a triangle or a rectangle.

[0190] In other embodiments, the first swing arm 2 is rotatably connected to the first mounting base 1 via the first shaft 13 .

[0191] The first shaft 13 may be an independent component, or may be a shaft structure integrated into the first swing arm 2 or the first mounting seat 1 .

[0192] For example, when the first shaft 13 is an independent component, the first shaft 13 is rotatably connected to one of the first swing arm 2 and the first mounting base 1, and is fixedly connected to the other. The following description takes the example of the first shaft 13 being fixedly connected to the first swing arm 2 and rotatably connected to the first mounting base 1.

[0193] Specifically, the fixed connection method and beneficial effects of the first shaft 13 and the first swing arm 2 can refer to the connection method and beneficial effects of the output shaft of the swing arm drive motor and the first swing arm 2 in the previous embodiment, and this application will not repeat them here.

[0194] like Figure 7 、 Figure 8 as well as Figure 19 As shown, the first shaft 13 is rotatably connected to the first mounting base 1 through the bearing base 16 and the motor connecting base 15.

[0195] Specifically, in the axial direction of the first shaft 13, the opposite ends of the motor connecting seat 15 are respectively connected to the swing arm drive motor and the first mounting seat 1. The end of the motor connecting seat 15 connected to the first mounting seat 1 is provided with a bearing seat 16 mounting groove for mounting a bearing seat 16. The bearing seat 16 assembled in the bearing seat 16 mounting groove protrudes from the surface of the motor connecting seat 15 facing the first mounting seat 1. The first mounting seat 1 has a through hole for accommodating the protruding portion of the bearing seat 16.

[0196] During assembly, the first shaft 13 and the bearing seat 16 are first rotatably connected via the bearing, and then the bearing seat 16 is connected to the motor connection seat 15. In specific implementation, the bearing seat 16 and the motor connection seat 15 can be connected via a threaded structure. Afterwards, the motor connection seat 15 is assembled to the first mounting seat 1, thus achieving a rotational connection between the first shaft 13 and the first mounting seat 1.

[0197] With this connection method, bearing seat 16 is not directly connected to first mounting seat 1. Therefore, when designing the thickness of mounting plate 101 within first mounting seat 1, there is no need to consider whether it can accommodate first mounting seat 1. This facilitates the rational design of mounting plate 101 and avoids material waste. Furthermore, bearing seat 16 protrudes from the surface of motor connection seat 15, and first mounting seat 1 is provided with a through hole for accommodating this protruding portion. This allows a portion of bearing seat 16 to overlap with mounting plate 101 along the axis of first shaft 13, thereby reducing the overall dimension of the motion assembly along the axis of first shaft 13 and achieving a more compact structure.

[0198] Of course, in specific implementation, if the thickness of the mounting plate 101 of the first mounting seat 1 meets the installation requirements of the bearing, the bearing can also be directly installed on the first mounting seat 1, so that the first shaft 13 and the first mounting seat 1 are directly connected through the bearing.

[0199] Furthermore, the output shaft of the swing arm drive motor is coaxially connected to the first shaft 13. In this arrangement, no transmission structure is required between the swing arm drive motor and the first shaft 13, which is conducive to simplifying the structure and reducing costs and failure rates.

[0200] Furthermore, the output shaft of the swing arm drive motor is connected to the first shaft 13 via a clamp structure. Compared to a spline connection between the output shaft of the swing arm drive motor and the first shaft 13, the first shaft 13 and the output shaft of the swing arm drive motor are fixedly connected by friction, with no clearance between the two, which effectively improves the stability of the motion assembly.

[0201] Furthermore, in some embodiments, the second swing arm 3 is rotatably connected to the first mounting base 1 via the second shaft 14 .

[0202] like Figure 5 As shown, the second shaft 14 can be a columnar structure integrated in the first mounting base 1, and a mounting hole is provided at one end of the second swing arm 3 connected to the first mounting base 1, and a bearing is provided in the mounting hole to connect with the columnar structure through the bearing, thereby realizing the rotational connection between the second swing arm 3 and the first mounting base 1.

[0203] In addition, the second shaft 14 may also be an independent component.

[0204] like Figure 21As shown, the second shaft 14 includes a fixing seat 1401 and a shaft body 1402 integrally formed with the fixing seat 1401 .

[0205] During assembly, the fixing seat 1401 is connected to the first mounting seat 1, and the shaft body 1402 is rotatably connected to the second swing arm 3 (the specific implementation method can be referred to above, and this application will not repeat it here).

[0206] Furthermore, the outer radius of the fixing seat 1401 is greater than the outer radius of the shaft body 1402. In this way, the stability of the connection between the second shaft 14 and the second mounting seat 4 can be effectively improved.

[0207] Of course, in some other embodiments, the second shaft 14 may be fixedly connected to the second swing arm 3 , and the second shaft 14 may be rotatably connected to the first fixing seat 1401 .

[0208] In some embodiments, as Figure 13 and Figure 14 As shown, the display screen assembly includes a drag chain 17. The drag chain 17 is used to protect and constrain the wiring harness. The wiring harness includes but is not limited to the power cord and data cable of the display screen 18.

[0209] The drag chain 17 is formed by connecting a plurality of links, and the links can rotate freely, and the drag chain 17 is in the shape of a crawler. The interior of the drag chain 17 has a receiving cavity, and the wire harness can be placed in the receiving cavity and pass through both ends of the length direction of the drag chain 17.

[0210] In this embodiment, one end of the drag chain 17 is connected to the display screen 18 , and the other end is connected to the second mounting base 4 .

[0211] As will be appreciated, when the display screen 18 moves relative to the second mounting base 4, the wiring harness connected to the display screen 18 will also move with it. In this embodiment, the wiring harness is constrained by a drag chain 17 to confine it within a controllable, regular, and low-friction channel. This prevents the wiring harness from making sharp bends, sharp bends, or excessive bends during movement, significantly reducing the risk of wire breakage and insulation damage. It also prevents interference between the wiring harness and other structural components during movement, thereby ensuring the reliability of the wiring harness connection.

[0212] In some embodiments, two groups of sliding mechanisms are provided, and the first driving assembly is located between the two groups of sliding mechanisms.

[0213] In this arrangement, the center of gravity of the entire display 18, the first drive assembly, and the sliding mechanism is located between the two sets of sliding mechanisms. Therefore, when the sliding mechanism controls the movement of the display 18 relative to the second mounting base 4, the problem of poor sliding caused by the center of gravity shift can be effectively alleviated or even avoided, thereby ensuring smoother movement of the display 18 relative to the second mounting base 4.

[0214] Furthermore, in the arrangement direction of the two sets of sliding mechanisms, the display screen 18 includes a first edge and a second edge;

[0215] The two sets of sliding mechanisms are respectively a first sliding mechanism and a second sliding mechanism; the first sliding mechanism is arranged close to the first edge, and the second sliding mechanism is arranged close to the second edge; and the distance between the first sliding mechanism and the first edge is equal to the distance between the second sliding mechanism and the second edge.

[0216] In this way, in the arrangement direction of the two sets of sliding mechanisms, the center of gravity of the whole formed by the display screen 18, the first drive assembly and the sliding mechanism is closer to the middle position, and the forces of the two sets of sliding mechanisms are more consistent, thereby making the movement of the display screen 18 relative to the second mounting bracket 4 smoother.

[0217] Furthermore, in the arrangement direction of the two sets of sliding mechanisms, the chain 1003 is located in the middle position of the two sets of sliding mechanisms, and the motor and the drag chain 17 are located on both sides of the chain 1003; this setting can further enhance the technical effect of smoother movement of the above-mentioned display screen 18 relative to the second mounting bracket 4.

[0218] In addition, if Figure 13 and Figure 14 As shown, in the first direction, the sprocket drive motor is arranged close to the lower end of the display screen 18. In this way, the center of gravity of the whole composed of the display screen 18, the first drive component and the sliding mechanism moves downward, which is more conducive to improving the stability of the display screen 18.
