Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to an in-vehicle display and a vehicle. Background Technology

[0002] With the rapid development of the automotive electronics industry, people have increasingly higher requirements for in-vehicle display products.

[0003] However, current in-vehicle displays have relatively wide bezels, resulting in larger overall dimensions and a more compact interior space, which can negatively impact heat dissipation. To improve this situation, the bezel width of the in-vehicle displays needs to be reduced to achieve a narrow bezel design, while simultaneously ensuring reliability and a good visual experience. This places high demands on the design of in-vehicle displays. Summary of the Invention

[0004] The vehicle-mounted display and vehicle provided in this application can achieve a narrow bezel design for the vehicle-mounted display while meeting the requirements of reliability and good visual effect.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide an in-vehicle display. The in-vehicle display area includes:

[0006] The bottom frame includes a bottom plate and a side plate. The side plate is disposed on one side of the bottom plate and is arranged around the circumference of the bottom plate, forming a receiving cavity with the bottom plate.

[0007] A light source, located on the bottom frame, is used to provide light;

[0008] A light guide plate is disposed on the base plate and located within the receiving cavity, for guiding and transmitting the light provided by the light source; wherein the light guide plate is spaced apart from the side plate at least on both sides along a first direction;

[0009] The light guide plate has a limiting protrusion on one side of the surface facing the base plate and a limiting groove on the other side of the surface facing the light guide plate. A first elastic member is provided on at least a first side of the limiting groove along the first direction, and the first elastic member extends along the first direction. The limiting protrusion is embedded in the limiting groove and abuts against the first elastic member along the first direction, so that the first elastic member is in an elastically compressed state.

[0010] In one embodiment of this application, a second elastic member is provided on the second side of the limiting groove along the first direction; the second elastic member extends along the first direction; the limiting protrusion is embedded in the limiting groove and abuts against the second elastic member along the first direction, so that the second elastic member is in an elastically compressed state;

[0011] Preferably, the distance between the first side of the light guide plate along the first direction and the side plate is 1mm-2mm; and / or the distance between the second side of the light guide plate along the first direction and the side plate is 1mm-2mm;

[0012] Preferably, the light guide plate is rectangular; the first direction is the length direction of the light guide plate.

[0013] In one embodiment of this application, the base plate is provided with a first groove and a second groove, the first groove and the second groove extending along the first direction respectively;

[0014] The base plate is further provided with a first sliding member and a second sliding member; the first sliding member is connected to the first elastic member and connected to the first slide groove, and the first sliding member can slide back and forth along the extension direction of the first slide groove to configure the first elastic member to different states; the second sliding member is connected to the second elastic member and connected to the second slide groove, and the second sliding member can slide back and forth along the extension direction of the second slide groove to configure the second elastic member to different states;

[0015] Preferably, the first groove and the second groove are located outside the extended path of the light guide plate along the first direction;

[0016] Preferably, the first slide groove and the second slide groove are symmetrically arranged along the first direction.

[0017] In one embodiment of this application, the inner wall surface of the first slide groove has a plurality of spaced first slots along the extending direction of the first slide groove, and the first sliding member is engaged in one of the first slots; and / or

[0018] The inner wall surface of the second slide groove has a plurality of spaced second slots along the extension direction of the second slide groove, and the second sliding member is engaged in one of the second slots;

[0019] Preferably, the contour of the first slot matches the outer contour of the first slider; and / or the contour of the second slot matches the outer contour of the second slider.

[0020] In one embodiment of this application, the width of the first groove is greater than the radial dimension of the first sliding member; and / or,

[0021] The width of the second groove is greater than the radial dimension of the second sliding member.

[0022] In one embodiment of this application, it further includes:

[0023] An elastic medium is disposed within the receiving cavity and at least on two opposing sides of the side plate along the first direction; wherein the light guide plate is spaced apart from the elastic medium on both sides along the first direction;

[0024] Preferably, the elastic medium is attached to the side plate in the circumferential direction and is arranged in a closed loop.

[0025] Preferably, the elastic medium includes a sealing strip.

[0026] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a vehicle, which includes a vehicle body and the aforementioned vehicle-mounted display, wherein the vehicle-mounted display is disposed on the vehicle body.

[0027] In one embodiment of this application, the vehicle body includes a seat headrest with a receiving groove on its back side. At least a portion of the vehicle display is received in the receiving groove, and the display surface of the vehicle display faces the side where the back of the seat headrest is located.

[0028] In one embodiment of this application, it further includes:

[0029] A ball joint assembly includes a connector and a rotating member. The connector is connected to the side of the base plate of the vehicle display facing away from the light guide plate, and the rotating member is connected to the connector and is configured to be rotatably connected to the vehicle body.

[0030] Preferably, the rotating component includes a spherical head; the vehicle body includes a spherical sleeve; and the spherical head is movably connected to the spherical sleeve.

[0031] In one embodiment of this application, the side surface of the base plate opposite to the light guide plate has a slide rail, and one end of the slide rail along its extension direction is an open end; the connector is slidably connected to the slide rail from the open end.

[0032] The beneficial effects of this application embodiment, which differ from the prior art, are as follows: The vehicle-mounted display provided in this application embodiment has a limiting protrusion on one surface of the light guide plate facing the base plate and a limiting groove on the other surface of the base plate facing the light guide plate. The limiting protrusion is embedded in the limiting groove, thereby enabling the light guide plate to be secured to the base frame. This solution not only achieves the connection and fixation between the light guide plate and the base frame, but also eliminates the need to use other filling materials such as silicone to fill the gap between the light guide plate and the base frame. This allows the light guide plate to be spaced apart from the side plate at least on both sides along the first direction, meaning that both sides of the light guide plate along the first direction are open ends. In this way, after the light guide plate expands due to heat, it can expand to both sides along the first direction. The expansion amount on each side of the light guide plate along the first direction is halved accordingly. This allows the vehicle-mounted display to minimize the bezel width along the first direction while meeting reliability and visual effects, thereby achieving a narrow bezel effect. Furthermore, this solution provides a first elastic member on at least a first side of the limiting groove along the first direction. The first elastic member extends along the first direction, and when the limiting protrusion is embedded in the limiting groove, the limiting protrusion abuts against the first elastic member along the first direction, and the first elastic member is in an elastically compressed state. In this way, it is not only convenient for the limiting protrusion to be embedded in the limiting groove, but the elastic restoring force of the first elastic member can also tightly clamp the limiting protrusion in the limiting groove, thereby reducing the risk of the limiting protrusion detaching from the limiting groove. Moreover, since the first elastic member is elastic, when the light guide plate expands due to heat on one or both sides along the first direction and abuts against the side plate, the force between the side plate and the light guide plate can further act on the first elastic member, causing the first elastic member to undergo elastic deformation, thereby causing the light guide plate to move towards the other side of the side plate, so as to buffer the force between the side plate and the light guide plate, reduce the risk of damage to the light guide plate and / or the side plate due to hard contact between the side plate and the light guide plate.

Detailed Implementation

[0043] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] The terms "first," "second," and "third" in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0045] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] In related technologies, automotive displays typically have two long sides and two short sides. The two sides containing the short sides are usually a wide side and a narrow side. The internal materials of the automotive display are assembled close to the narrow side, while the wide side is an open end, meaning it is spaced apart from the side panel of the bottom frame. However, due to the significant expansion of the light guide plate and the internal materials of the automotive display (for example, the expansion along the length of a 12.3-inch display is 1.4mm), insufficient space at the open end can lead to insufficient expansion space for the internal materials, causing problems such as high-temperature film arching. Furthermore, if the bezel of the automotive display is too narrow, the light guide plate will be too close to the viewable area, causing bright edges and poor visual effects.

[0047] Therefore, this application provides a new vehicle display. By locking the light guide plate with the limiting protrusion and limiting groove on the base plate, both ends of the light guide plate along the first direction are open. In this way, after the light guide plate is heated and expands, it can expand to both sides along the first direction. The expansion amount on each side of the light guide plate along the first direction is halved accordingly. This allows the vehicle display to minimize the width of the bezel along the first direction while meeting reliability and visual effect requirements, thereby achieving a narrow bezel effect.

[0048] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] Please see Figures 1 to 2 , Figure 1 This is a schematic diagram showing the position between the light guide plate and the base plate according to an embodiment of this application; Figure 2 This is a vertical cross-sectional view of the light guide plate and the bottom frame after they are connected according to the first embodiment of this application. In this embodiment, a vehicle display 10 is provided, which includes a bottom frame 11, a light source (not shown) and a light guide plate 12.

[0050] The bottom frame 11 includes a bottom plate 111 and a side plate 112. The bottom plate 111 is configured to be connected to the vehicle body. The side plate 112 is disposed on one side of the bottom plate 111 and is arranged around the bottom plate 111 in a circumferential manner, that is, the side plate 112 is distributed along the outer edge contour of the bottom plate 111 and forms a receiving cavity with the bottom plate 111.

[0051] For example, the base plate 111 is rectangular in shape, and there are four side plates 112. Each side plate 112 is disposed on each side of the base plate 111 and faces the same direction, with an included angle between adjacent side plates 112. Of course, the overall shape of the base plate 111 can also be circular, triangular, trapezoidal or irregular polygonal, and it is preferably rectangular in this embodiment.

[0052] In one embodiment, the base plate 111 can be formed by stamping metal material, and each side plate 112 is formed by bending the base plate 111; in other embodiments, the user can also change the material of the base plate 111, such as plastic, according to actual needs.

[0053] A light source is located on the bottom frame 11 to provide light. This light source can be a light strip, which is positioned along the length of the side plate 112. The light strip can be bonded to the side of the side plate 112 near the receiving cavity using thermally conductive adhesive. An FPC (Flexible Printed Circuit) board is soldered to the light strip, and the FPC board can be bonded to the other side plate 112.

[0054] A light guide plate 12 is disposed on the base plate 111 and located within the receiving cavity, for guiding and transmitting light provided by the light source. The light guide plate 12 is spaced apart from the side plate 112 at least on both sides along a first direction X. For example, the light guide plate 12 may be rectangular in shape; the first direction X may be the length direction of the light guide plate 12; that is, the two short sides of the light guide plate 12 are spaced apart from the side plate 112 to provide a certain expandable space when the light guide plate 12 undergoes thermal expansion along the first direction X during operation, thereby improving product reliability.

[0055] In one example, combined Figure 2 The distance S1 between the first side of the light guide plate 12 along the first direction X and the side plate 112 is 1mm-2mm; for example, the distance S1 can be 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, or 2.0mm. In another example, the distance S2 between the second side of the light guide plate 12 along the first direction X and the side plate 112 is 1mm-2mm; for example, the distance S2 can be 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, or 2.0mm. In yet another example, the distance S1 between the first side of the light guide plate 12 along the first direction X and the side plate 112 is 1mm-2mm; and the distance S2 between the second side of the light guide plate 12 along the first direction X and the side plate 112 is 1mm-2mm.

[0056] Among them, combined Figure 2The light guide plate 12 has a limiting protrusion 121 on one side of its surface facing the base plate 111, and the other surface has a limiting groove 113. The limiting protrusion 121 is embedded in the limiting groove 113 to achieve a snap-fit ​​connection between the light guide plate 12 and the base plate 111.

[0057] This solution not only achieves the connection and fixation between the light guide plate 12 and the bottom frame 11, but also eliminates the need to use other filler materials such as silicone to fill the gap between the light guide plate 12 and the bottom frame 11 to achieve the connection. This allows the light guide plate 12 to be spaced apart from the side plate 112 at least on both sides along the first direction X, meaning both sides of the light guide plate 12 along the first direction X are open ends. This allows the light guide plate 12 to expand to both sides along the first direction X after being heated, with the expansion amount on each side of the light guide plate 12 being halved accordingly. This allows the vehicle display 10 to minimize the bezel width along the first direction X while meeting reliability and visual effect requirements, thus achieving a narrow bezel effect. Furthermore, the area originally used for filler material can be converted into a light guide plate 12 to increase the visible area of ​​the vehicle display 10 and reduce the bezel size.

[0058] For example, a limiting groove 113 can be formed on the side surface of the base plate 111 facing the light guide plate 12, and a limiting protrusion 121 can be formed on the side surface of the light guide plate 12 facing the base plate 111. The dimension of the limiting protrusion 121 along the first direction X can be smaller than the dimension of the limiting groove 113 along the first direction X; the dimension of the limiting protrusion 121 along the second direction Y, which is perpendicular to the first direction X, is smaller than the dimension of the limiting groove 113 along the second direction Y. This not only facilitates the embedding of the limiting protrusion 121 into the limiting groove 113, but also allows the limiting protrusion 121 to move along the first direction X within the limiting groove 113, thereby reducing the risk of the light guide plate 12 rigidly contacting the side plate 112 after thermal expansion.

[0059] For example, the limiting groove 113 can be located at the middle position of the base plate 111 along the first direction X, that is, the limiting groove 113 is equidistant from the two side edges of the base plate 111 along the first direction X. The limiting protrusion 121 is located at the middle position of the light guide plate 12 along the first direction X, that is, the limiting protrusion 121 is equidistant from the two side edges of the light guide plate 12 along the first direction X.

[0060] Please continue reading. Figure 2The limiting groove 113 has a first side and a second side along the first direction X. In some embodiments, the limiting groove 113 is provided with a first elastic member 13a along at least the first side along the first direction X. The first elastic member 13a extends along the first direction X. When the limiting protrusion 121 is embedded in the limiting groove 113, the limiting protrusion 121 abuts against the first elastic member 13a along the first direction X, and the first elastic member 13a is in an elastically compressed state.

[0061] In this way, by compressing the first elastic member 13a, the dimension between the first elastic member 13a and the second side of the limiting groove 113 is made larger than the dimension of the limiting protrusion 121 along the first direction X, so that the limiting protrusion 121 can be embedded in the limiting groove 113; and after the limiting protrusion 121 is embedded in the limiting groove 113, the first elastic member 13a moves toward the second side of the limiting groove 113 under the action of its own elastic restoring force, thereby tightly clamping the limiting protrusion 121 in the limiting groove 113, thereby reducing the risk of the limiting protrusion 121 detaching from the limiting groove 113. Furthermore, since the first elastic element 13a is elastic, when the light guide plate 12 expands due to heat along one or both sides of the first direction X and comes into contact with the side plate 112, the force between the side plate 112 and the light guide plate 12 can further act on the first elastic element 13a, causing the first elastic element 13a to undergo elastic deformation, thereby causing the light guide plate 12 to move toward the other side of the side plate 112, so as to buffer the force between the side plate 112 and the light guide plate 12, reduce the risk of damage to the light guide plate 12 and / or the side plate 112 due to hard contact between the side plate 112 and the light guide plate 12.

[0062] The first elastic element 13a can be an elastic structure such as a spring or a coil spring.

[0063] In one embodiment, see Figure 3 , Figure 3 This is a vertical cross-sectional view of the light guide plate 12 and the bottom frame 11 after being connected according to the second embodiment of this application. A second elastic member 13b is provided on the second side of the limiting groove 113 along the first direction X; the second elastic member 13b extends along the first direction X; when the limiting protrusion 121 is embedded in the limiting groove 113, the light guide plate 12 abuts against the second elastic member 13b along the first direction X, and the second elastic member 13b is in an elastically compressed state.

[0064] In this way, the elastic restoring force of the second elastic member 13b can enhance the locking force on the limiting protrusion 121, thereby further reducing the risk of the limiting protrusion 121 detaching from the limiting groove 113. Moreover, by providing an elastic member on each side of the limiting groove 113, and making the limiting protrusion 121 abut against the first elastic member 13a and the second elastic member 13b on both sides along the first direction X respectively, regardless of which side of the light guide plate 12 deforms more due to thermal expansion along the first direction X, the light guide plate 12 can be moved towards the other side by compressing the elastic member on the other side, thereby reducing the probability of the light guide plate 12 hard contacting the side plate 112.

[0065] The first elastic element 13a and the second elastic element 13b can be two structures with identical structure, performance and parameters to ensure that the first elastic element 13a and the second elastic element 13b can apply the same force to the light guide plate 12. Thus, when the light guide plate 12 and the side plate 112 are spaced apart, the light guide plate 12 is positioned in the middle of the cavity along the first direction X, reducing the insufficient spacing between the side of the light guide plate 12 along the first direction X and the side plate 112, which can cause the light guide plate 12 to be squeezed towards the middle and cause the film arch when heated.

[0066] Of course, in other examples, the structures of the first elastic element 13a and the second elastic element 13b may also be different.

[0067] In some embodiments, please refer to Figure 4 and Figure 5 , Figure 4 A schematic diagram showing the positions of the first slider 14a and the second slider 14b on the base plate 111 according to an embodiment of this application; Figure 5 This is a vertical cross-sectional view of the light guide plate 12 and the bottom frame 11 after they are connected according to the third embodiment of this application. The bottom plate 111 is also provided with a first groove 114 and a second groove 115 on the side of the bottom plate 111 facing the light guide plate 12. The first groove 114 and the second groove 115 extend along the first direction X, respectively.

[0068] The base plate 111 is also provided with a first sliding member 14a and a second sliding member 14b; the first sliding member 14a is connected to the first elastic member 13a and connected to the first slide groove 114, and the first sliding member 14a can slide back and forth along the extension direction of the first slide groove 114 to configure the first elastic member 13a to different states. The different states include different compression states and an initial state without compression. In other words, the user can apply force to the first sliding member 14a to move the first sliding member 14a back and forth along the extension direction of the first groove 114, thereby controlling the compression state of the first elastic member 13a. As the limiting protrusion 121 is embedded into the limiting groove 113, the first elastic member 13a is further elastically compressed to increase the distance between the two elastic members along the first direction X, so that the limiting protrusion 121 can be embedded into the limiting groove 113. After the limiting protrusion 121 is embedded into the limiting groove 113, the first elastic member 13a is moved toward the center position of the limiting groove 113 along the first direction X to clamp the limiting protrusion 121.

[0069] The second sliding member 14b is connected to the second elastic member 13b and to the second slide groove 115. The second sliding member 14b can slide back and forth along the extension direction of the second slide groove 115 to configure the second elastic member 13b to different states. Similarly, the different states include different compression states and an initial state without compression. Likewise, the user can apply a force to the second sliding member 14b to move it back and forth along the extension direction of the second slide groove 115 to control the compression state of the second elastic member 13b. This allows the second elastic member 13b to be further elastically compressed during the process of the limiting protrusion 121 being inserted into the limiting groove 113, thereby increasing the distance between the two elastic members along the first direction X, facilitating the insertion of the limiting protrusion 121 into the limiting groove 113. After the limiting protrusion 121 is inserted into the limiting groove 113, the second elastic member 13b moves toward the center position of the limiting groove 113 along the first direction X to further clamp the limiting protrusion 121.

[0070] Among them, combined Figure 4 The first slide groove 114 and the second slide groove 115 can be located outside the extended path of the light guide plate 12 along the first direction X. This can prevent the first slider 14a and the second slider 14b from hindering the thermal expansion process of the light guide plate 12 along the first direction X.

[0071] For example, the first slide groove 114 and the second slide groove 115 can be symmetrically arranged along the first direction X. In this way, when the distance between the first slider 14a and the second slider 14b is small, the two sliders, the first slider 14a and the second slider 14b, can be slid simultaneously by the cooperation of the thumb and the index finger, which is convenient for operation.

[0072] In some embodiments, see Figure 6 , Figure 6 This is a schematic diagram of the structure of the first slide groove 114 and the second slide groove 115 provided in an embodiment of this application; the inner wall surface of the first slide groove 114 has a plurality of spaced first slots 114a along the extension direction of the first slide groove 114, and the first sliding member 14a is engaged in one of the first slots 114a to fix the position of the first sliding member 14a in the first slide groove 114 through the first slot 114a.

[0073] By providing multiple first slots 114a, the first sliding member 14a can be fixed at different positions in the first sliding groove 114. The specific number of first slots 114a can be set according to the actual situation.

[0074] In some embodiments, the inner wall surface of the second slide groove 115 has a plurality of spaced second slots 115a along the extending direction of the second slide groove 115, and the second slider 14b is engaged in one of the second slots 115a to fix the position of the second slider 14b in the second slide groove 115 through the second slot 115a.

[0075] By providing multiple second slots 115a, the second slider 14b can be fixed at different positions in the second slide groove 115. The specific number of second slots 115a can be set according to the actual situation.

[0076] In some embodiments, the inner wall surface of the first slide groove 114 has a plurality of spaced first slots 114a along the extending direction of the first slide groove 114, and the inner wall surface of the second slide groove 115 has a plurality of spaced second slots 115a along the extending direction of the second slide groove 115, so as to limit the first slider 14a and the second slider 14b respectively.

[0077] The contour of the first slot 114a matches the outer contour of the first slider 14a; and / or the contour of the second slot 115a matches the outer contour of the second slider 14b. The first slider 14a and the second slider 14b can be cylinders; the first slot 114a and the second slot 115a can be semi-circular slots.

[0078] In some embodiments, the width of the first groove 114 is greater than the radial dimension of the first slider 14a. The width of the second groove 115 is greater than the radial dimension of the second slider 14b. Of course, in other embodiments, the width of the first groove 114 may be greater than the radial dimension of the first slider 14a; or the width of the second groove 115 may be greater than the radial dimension of the second slider 14b. Here, the groove width refers to the dimension along the second direction Y of the groove; the radial dimension refers to the maximum diameter of the corresponding slider passing through its center.

[0079] In some embodiments, see Figure 7 , Figure 7 This is a top view of the light guide plate 12 and the base plate 111 provided in an embodiment of this application after being connected; the vehicle display 10 also includes an elastic medium 15, which is disposed in the receiving cavity and at least on two opposite sides of the side plate 112 along the first direction X; wherein, the light guide plate 12 is spaced apart from the elastic medium 15 at least on both sides along the first direction X.

[0080] In this embodiment, by adding an elastic medium 15 within the receiving cavity, the size of the receiving cavity along the first direction X can be reduced by using elastic mediums 15 of different sizes. This allows the receiving cavity to accommodate a smaller light guide plate 12 to fit vehicle-mounted displays 10 of different sizes. Furthermore, even after adding the elastic medium 15, the light guide plate 12 is still spaced apart from the elastic medium 15 at least on both sides along the first direction X. This provides sufficient expansion space for the light guide plate 12 when it undergoes thermal expansion along the first direction X during operation, thereby improving product reliability.

[0081] For example, in combination Figure 7 The elastic medium 15 can be attached to the side plate 112 in the circumferential direction and form a closed loop. The elastic medium 15 may include a sealing strip; for example, a plastic or rubber strip.

[0082] In any of the above embodiments, the light guide plate 12 may be further spaced apart from the side plate 112 on both sides along the second direction Y, so as to provide a certain expandable space when the light guide plate 12 undergoes thermal expansion along the second direction Y during operation, thereby improving the reliability of the product. Of course, the light guide plate 12 may also directly contact the side plate 112 or the elastic medium 15 on both sides along the second direction Y, so as to reduce the bezel of the vehicle display 10 along the second direction Y.

[0083] The vehicle display 10 provided in this embodiment has a limiting protrusion 121 on one of the surfaces of the light guide plate 12 facing the base plate 111 and the other surface of the base plate 111 facing the light guide plate 12, and a limiting groove 113 on the other surface. The limiting protrusion 121 is embedded in the limiting groove 113, so that the light guide plate 12 is snapped onto the base frame 11. This solution not only enables the connection and fixation between the light guide plate 12 and the bottom frame 11, but also eliminates the need to fill the gap between the light guide plate 12 and the bottom frame 11 with other filler materials such as silicone. This allows the light guide plate 12 to be spaced apart from the side plate 112 at least on both sides along the first direction X, meaning that both sides of the light guide plate 12 along the first direction X are open ends. In this way, after the light guide plate 12 is heated and expands, it can expand to both sides along the first direction X. The expansion amount on each side of the light guide plate 12 along the first direction X is halved accordingly. This allows the vehicle display 10 to minimize the width of the bezel along the first direction X while meeting reliability and visual effects, thereby achieving a narrow bezel effect. Furthermore, this solution provides a first elastic member 13a on at least a first side of the limiting groove 113 along the first direction X. The first elastic member 13a extends along the first direction X. When the limiting protrusion 121 is embedded in the limiting groove 113, the limiting protrusion 121 abuts against the first elastic member 13a along the first direction X, and the first elastic member 13a is in an elastically compressed state. In this way, it is not only convenient for the limiting protrusion 121 to be embedded in the limiting groove 113, but the elastic restoring force of the first elastic member 13a can also tightly clamp the limiting protrusion 121 in the limiting groove 113, thereby reducing the risk of the limiting protrusion 121 falling out of the limiting groove 113. The risk of detachment within the slot 113; and because the first elastic member 13a is elastic, when the light guide plate 12 expands due to heat along one or both sides of the first direction X and comes into contact with the side plate 112, the force between the side plate 112 and the light guide plate 12 can further act on the first elastic member 13a, causing the first elastic member 13a to undergo elastic deformation, thereby causing the light guide plate 12 to move toward the other side of the side plate 112, so as to buffer the force between the side plate 112 and the light guide plate 12, reduce the risk of hard contact between the side plate 112 and the light guide plate 12, and damage to the light guide plate 12 and / or the side plate 112.

[0084] In some embodiments, see Figure 8 , Figure 8 This is a simplified structural diagram of the ball joint assembly provided in one embodiment of the present application after being connected to the vehicle-mounted display and the spherical sleeve; a vehicle is provided, which can be any vehicle including the vehicle-mounted display 10. Exemplarily, the vehicle can be a new energy vehicle (e.g., an electric vehicle), an electric motorcycle, etc. The vehicle includes the vehicle-mounted display 10 and a vehicle body (not shown) provided in any of the above embodiments. The vehicle body includes the body frame, wheels, seats, etc. The specific structure and function of the vehicle-mounted display 10 can be found in the relevant description above.

[0085] In some embodiments, the vehicle further includes a ball joint assembly 21 configured to connect the vehicle display 10 to the vehicle body. The ball joint assembly 21 includes a connector 211 and a rotator 212, the connector 211 being connected to the side of the base plate 111 of the vehicle display 10 opposite to the light guide plate 12.

[0086] In some embodiments, the base plate 111 has a slide rail (not shown) on the side surface opposite to the light guide plate 12, with one end of the slide rail being an open end along its extension direction; the connector 211 is slidably connected to the slide rail from the open end. In this way, the position of the vehicle display 10 relative to the vehicle body in a certain direction (such as vertical or horizontal position) can be adjusted by moving the connector 211 back and forth within the slide rail; the connector 211 can also be slid out of the slide rail to remove the vehicle display 10 from the ball joint assembly 21, making the removal and installation of the vehicle display 10 relatively convenient.

[0087] Of course, in other embodiments, the slide rail may also be formed on the side surface of the connector 211 facing the vehicle display 10; the side surface of the base plate 111 opposite to the light guide plate 12 has a sliding block, which is embedded in the slide rail to realize the relative sliding between the vehicle display 10 and the ball head assembly 21.

[0088] The rotating component 212 is connected to the connector 211 and is configured to be rotatably connected to the vehicle body to enable the vehicle display 10 to rotate relative to the vehicle body.

[0089] In some embodiments, the rotating member 212 includes a spherical head, and the vehicle body includes a spherical sleeve 22; the spherical head is movably connected within the spherical sleeve 22; thus, by utilizing the movable connection between the spherical sleeve 22 and the spherical head, the ball head assembly 21 can be rotated 360° relative to the spherical sleeve 22, thereby making the vehicle display 10 visible in all directions.

[0090] In some embodiments, the vehicle body also includes a seat headrest (not shown), the back of which has a receiving groove, in which at least a portion of the vehicle display 10 is received, with the display surface of the vehicle display 10 facing the side where the back of the seat headrest is located. Thus, the vehicle display 10 can be viewed by a user in the rear seat. Specifically, the vehicle display 10 can be quickly installed and removed from the receiving groove using locking and positioning structures such as nuts and studs.

[0091] Of course, in other embodiments, the vehicle display 10 can also be directly mounted on the side where the driver's seat is located for the driver to view.

[0092] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
