Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted equipment, and in particular to a vehicle-mounted device, a display device, an audio device and a terminal. Background Art

[0002] As people's demands for the comfort, safety, convenience and other in-vehicle functions of mobile terminals (such as vehicles, ships, airplanes and other means of transport) continue to increase, more and more intelligent, digital and networked devices are integrated into mobile terminals. Taking vehicles as an example, rear LCD screens, rear projection equipment, in-car audio, etc. are gradually being widely used in large, medium and small passenger cars, commercial vehicles and engineering vehicles, etc., fully enabling the performance improvement of the cockpit and the improvement of the riding experience.

[0003] However, these intelligent devices also pose a hidden danger to passenger safety. Since vehicles and other mobile terminals need to move in the external environment, they often encounter acceleration, sudden braking, collisions, bumps and other scenes. Many casualties caused by car accidents are caused by cuts and scratches from equipment and its parts that have fallen off, deformed, or broken. Especially in the case where vehicle-mounted devices are installed in the front seats of the vehicle, if the vehicle collides, brakes suddenly, etc., the rear passengers will impact the front seats at high speed. At this time, if the vehicle-mounted device installed in the front seat is hit and falls off or breaks, it will cause serious injuries to the rear passengers.

[0004] Therefore, how to improve the anti-collision performance of the vehicle-mounted device is a hot issue that technicians in this field are currently studying. Summary of the invention

[0005] The embodiments of the present application provide a vehicle-mounted device, a display device, an audio device and a terminal, which can significantly improve the anti-collision performance of the vehicle-mounted device and enhance the protection of the user's personal safety.

[0006] In a first aspect, an embodiment of the present application provides a vehicle-mounted device, which includes a shell and a panel. At least a portion of the shell surrounds a cavity. The panel is used to close the cavity, and the panel is provided with a connection hole. The panel is fixedly mounted on the shell through an energy absorbing component, and the energy absorbing component includes an adhesive layer and a first connection structure, the adhesive layer is arranged between the panel and the shell and is used to bond the panel and the shell, and the first connection structure is used to assemble with the connection hole to achieve a fixed connection between the panel and the shell.

[0007] Optionally, the vehicle-mounted device may be installed in a mobile terminal, such as in a seat of the mobile terminal, or on the top of a cabin of the mobile terminal.

[0008] In some mobile terminals, the panel set on the cavity may sink into the cavity when hit, resulting in risks of falling off, deformation, and cracking, threatening the personal and property safety of users. However, the present application sets an energy absorbing component in the vehicle-mounted device, which is used to fix the panel and conduct and disperse the impact force on the panel when the panel is hit.

[0009] On the one hand, the energy absorbing component includes an adhesive layer. The adhesive interface formed by the adhesive layer between the panel and the shell can provide a reaction force when the panel is subjected to an external force, thereby reducing the possibility of deformation and falling off of the panel. On the other hand, the energy absorbing component also includes a first connection structure. The assembly between the first connection structure and the connection hole of the panel can achieve relative fixation between the panel and the structural member, ensuring a tight connection between the panel and the structural member, thereby further reducing the risk of falling off and cracking of the panel due to large deformation.

[0010] When an object hits the panel or a component outside the panel, the impact force is transmitted to the shell through the adhesive layer and / or the first connecting structure when it reaches the panel, making the panel less prone to risks of deformation, falling off, or cracking, thereby significantly improving the anti-collision performance of the vehicle-mounted device and enhancing the protection of user personal safety.

[0011] In a possible implementation, the first connection structure may include a pin, a buckle, and other structures capable of achieving a fixed connection. The following description will take the first connection structure being a pin as an example.

[0012] In a possible implementation, the first connection structure may be provided on the housing. In some embodiments, the housing includes an integral middle housing, and the pin may be integrally connected to the middle housing, that is, the housing (i.e., the middle housing) has a pin. In some embodiments, the housing includes a plurality of components (described below) that are separately provided, and the pin may be integrally connected to a portion (e.g., one of) the components in the housing, that is, a portion of the components included in the housing has a pin.

[0013] In a possible embodiment, the main body of the shell is used to enclose and form the cavity, and the shell also has a first connection structure, and the first connection structure of the shell is assembled with the connection hole of the panel to achieve a fixed connection between the shell and the panel. That is, the aforementioned shell can be regarded as an integrated structure. In this embodiment, the shell not only forms a cavity, but also is used to achieve the fixation and collision protection of the panel. No other structural parts are introduced, and the collision protection requirements can be met at a reduced cost.

[0014] Optionally, an adhesive layer may be provided between the housing (or the main body of the housing) and the panel. Furthermore, in the case where the first connection structure is a pin, the gap between the pin and the panel may also be filled with an adhesive material, thereby further improving the stability of the assembly of the pin and the connection hole, and the adhesive material may also be regarded as an adhesive layer.

[0015] In a possible implementation of the first aspect, the shell includes a middle shell and a structural member. The panel is fixedly mounted on the structural member through the energy absorbing assembly. The first connecting structure is arranged on a side of the structural member facing the panel, and the adhesive layer is arranged between the panel and the structural member.

[0016] In other words, in some solutions, the middle shell and the structural member are separately arranged. In the above embodiment, the shell includes a shell and a structural member, the shell is used to surround and form a cavity, and the structural member is used to fix and prevent collision of the panel, thereby achieving decoupling of different functional components. For example, the structural member can adopt a more rigid structure due to the force, thereby improving the stability of the overall mechanism.

[0017] Optionally, the structural member is located between the middle shell and the panel. When the panel is hit and generates an impact force in the direction of the cavity, the adhesive layer and the first connection structure on the structural member can fix the panel, and the structural member can also provide support force to the panel, further improving the anti-collision performance of the vehicle-mounted device.

[0018] In another possible implementation manner of the first aspect, the structural member is fixedly connected to the middle shell. By fixedly connecting the structural member and the middle shell, the stability of the overall structure can be improved.

[0019] In another possible implementation of the first aspect, the structural member is at least partially disposed on a side of the panel away from the cavity. In this way, at least a portion of the panel may be surrounded by the structural member, and in some cases the impact point may be transferred to the structural member, further improving the anti-collision performance of the vehicle-mounted device.

[0020] For example, when an object hits the panel, the impact force is transmitted to the structural parts and other components through the adhesive layer and the first connecting structure after reaching the panel, which is equivalent to the structural parts providing "pulling force" for the panel, making the panel less likely to deform, fall off, break, and other unexpected situations.

[0021] In another possible implementation of the first aspect, the structural member includes a bottom plate and a side wall, wherein the side wall is arranged around the bottom plate, the bottom plate is annular and covers the edge of the panel, a first connecting structure is provided on a side of the bottom plate facing the panel, and the side wall is arranged around the periphery of the middle shell.

[0022] In this embodiment, when an impact object hits the side wall and panel of a structural member, the impact force generated by the impact can be promptly transmitted to the structural member, the housing, etc., thereby improving the anti-collision capability of the vehicle-mounted device.

[0023] In yet another possible implementation manner of the first aspect, the vehicle-mounted device further includes a fixed connection structure, and the fixed connection structure is used to fixedly connect the shell and the seat.

[0024] In this embodiment, the shell is mounted on the seat and fixedly connected to the seat via a fixed connection structure, so that the impact force on the vehicle-mounted device can be quickly transmitted to the seat, further improving the anti-collision capability of the vehicle-mounted device.

[0025] In another possible implementation of the first aspect, the fixed connection structure includes a rotating shaft fixing member and a rotating shaft cantilever, wherein: the rotating shaft fixing member is fixedly connected to the middle shell, the rotating shaft fixing member has a protruding rotating shaft, the rotating shaft cantilever is provided with a rotating shaft connecting hole, the rotating shaft connecting hole is used to assemble with the rotating shaft to realize the rotation of the rotating shaft cantilever around the rotating shaft, and the rotating shaft cantilever includes a second connecting structure, and the second connecting structure is used to realize the fixed connection between the rotating shaft cantilever and the seat.

[0026] In the above embodiment, the stability of the vehicle-mounted device when subjected to external forces (such as vibration, impact, etc.) can be improved by adding a rotating shaft cantilever to a rotating shaft. In addition, the structure of the rotating shaft cantilever combined with the fixed rotating shaft further improves the stability and anti-collision capability of the vehicle-mounted device.

[0027] In another possible implementation of the first aspect, one end of the rotating shaft fixing member abuts against the structural member. In this way, the force transmitted to the structural member can be directly transmitted to the seat through the fixing member and the rotating shaft cantilever, and the seat can provide a fixing and buffering effect for the vehicle-mounted device, further improving the anti-collision capability of the vehicle-mounted device.

[0028] In another possible implementation of the first aspect, the structural member is fixedly connected to the seat. In this way, on the one hand, the stability of the overall structure can be improved, and on the other hand, the force transmitted to the structural member can be directly transmitted to the seat through the fixed connection, and the seat can provide a fixing and buffering effect for the vehicle-mounted device, further improving the anti-collision capability of the vehicle-mounted device.

[0029] In another possible implementation of the first aspect, the structural member is a metal member, wherein the metal may be an alloy, a pure metal, etc. Since metal has relatively high rigidity, it is more conducive to fixing the panel and transmitting the impact force, which can further enhance the anti-collision capability of the vehicle-mounted device.

[0030] In yet another possible implementation of the first aspect, the seat includes a headrest, and the vehicle-mounted device is disposed on the headrest of the seat.

[0031] In yet another possible implementation manner of the first aspect, the seat includes a backrest, and the vehicle-mounted device is disposed on the backrest of the seat.

[0032] In yet another possible implementation manner of the first aspect, the seat includes a headrest, a backrest, and a connecting portion connecting the backrest and the headrest, and the vehicle-mounted device is disposed on the connecting portion.

[0033] Optionally, the headrest and backrest of the seat can be provided separately or in one piece.

[0034] In another possible implementation of the first aspect, the panel is arranged on a side of the seat facing the rear of the mobile terminal. Thus, through the above implementation, the risk of panel deformation, falling off, or even breaking of the vehicle-mounted device due to collision can be reduced, thereby ensuring the life safety of rear passengers.

[0035] In another possible implementation of the first aspect, the shell is provided with a protrusion, the protrusion extends in a direction from the shell to the panel, the top end of the protrusion abuts the panel, and the adhesive layer is provided on a side of the protrusion away from the center of the panel.

[0036] In the above embodiment, by setting the protrusion, the adhesive layer can be provided with a supporting force away from the impact point, so that the adhesive layer 103 is not easy to deform and displace. On the one hand, the stability of the overall structure can be improved and the anti-collision performance of the device can be improved. On the other hand, debonding due to impact can be avoided to improve the aesthetics of the vehicle-mounted device.

[0037] In another possible implementation of the first aspect, the adhesive layer includes a flexible member having adhesiveness. On the one hand, the adhesiveness of the flexible member can enable the adhesive layer to form an adhesive interface between the housing and the panel, thereby improving stability, and on the other hand, the flexible member can provide a buffering effect when the panel is hit, thereby improving the anti-collision performance of the device.

[0038] Optionally, the bonding layer can be achieved by filling with glue, in which case the surface layer of the glue is sticky, while the middle part of the glue can serve as a buffer layer to play a buffering role.

[0039] Optionally, the adhesive layer may be a double-adhesive foam, which includes two layers of adhesive and a foam layer between the two layers of adhesive. The two layers of adhesive may form an adhesive interface between the housing and the panel, and the foam layer may play a buffering role to improve the stability and anti-collision performance of the vehicle-mounted device.

[0040] In another possible implementation of the first aspect, the panel is made of a fragile material. Exemplarily, the panel is a glass panel.

[0041] In another possible implementation of the first aspect, the panel is a composite glass panel, and the composite glass panel comprises an inorganic material layer and an organic material layer stacked together. Optionally, the composite glass panel further comprises a film, and the film covers the inorganic material layer and / or the organic material layer.

[0042] In yet another possible implementation of the first aspect, the thickness of the inorganic material layer is greater than or equal to 2 mm, and the thickness of the organic material layer is greater than or equal to 2 mm.

[0043] In another possible implementation of the first aspect, the vehicle-mounted device further includes a signal source, and the signal source is located in the cavity.

[0044] The signal source is used to generate a signal, and the signal is transmitted to the object space through the cavity and the panel. The signal includes but is not limited to light, sound waves, electromagnetic waves and other signals.

[0045] In this embodiment, the cavity of the vehicle-mounted device can form the function of the signal conduction path to complete its specific function. For example, when the signal is light, a variety of optical elements can be set in the cavity, and the light can produce reflection, refraction and other phenomena in the optical elements in the cavity, and the cavity can not only provide space for the path design of the light, but also achieve the effect of water drainage and dust prevention, thereby improving the service life of the vehicle-mounted device. For another example, when the signal is a sound wave, the multiple reflections of the sound wave by the cavity can improve the sound playback effect and enhance the user experience.

[0046] In a second aspect, an embodiment of the present application provides a display device, the display device comprising an image generating unit and a vehicle-mounted device according to any one of the first aspects. At least part of the housing in the vehicle-mounted device surrounds a cavity. The image generating unit is located in the cavity and is used to generate a light beam, which is transmitted through the cavity and the panel in the vehicle-mounted device to the object space outside the display device to generate a virtual image visible to the human eye.

[0047] Optionally, the display device is installed in the seat of the movable terminal.

[0048] In a possible implementation manner of the second aspect, the display device further includes an optical element, which is disposed in the cavity and is used to process the light beam.

The audio device is installed in a seat of a mobile terminal, the housing comprises a cavity, and the speaker is used to generate sound waves, which can be propagated to a physical space outside the audio device.

[0050] Optionally, sound waves may pass through the cavity and a panel in the vehicle-mounted device.

[0069] In recent years, more and more intelligent, digital, and networked devices have been integrated into mobile terminals. While these devices have brought performance improvements and optimized user experience to mobile terminals, they have also brought more risks to the use of mobile terminals.

[0070] See also Figure 1 , Figure 1 1 is a schematic diagram of an application scenario of a vehicle-mounted device provided in an embodiment of the present application, wherein the vehicle-mounted device 10 can be installed in a seat of a vehicle. Figure 1 In part (a), the vehicle-mounted device 10 is placed in the seat of the vehicle and faces the rear of the vehicle. For example, when the rear passengers are riding in the vehicle, they can watch movies, browse the web, watch videos on demand, or play games through the vehicle-mounted device 10 placed on the front seat. Figure 1 As shown in part (b) of FIG. 1 , if the vehicle collides or brakes suddenly, the rear passengers will hit the front seats at high speed and are likely to collide with the vehicle-mounted device 10. The vehicle-mounted device 10 is likely to deform, fall off, or break due to the impact force of the collision, causing serious injuries to the rear passengers. In particular, the heads of the rear passengers are likely to hit the vehicle-mounted device 10, endangering the personal safety of the passengers.

[0071] Especially for vehicles with built-in cavity spaces, such as display devices, audio devices and other equipment, when the panels of these devices are hit by external force, they will sink inward. Since there are no parts that can bear the force in the cavity, it is very easy for the panel of the device to deform, fall off, break and other unexpected situations, posing a threat to the personal safety of users.

[0072] In view of this, the embodiments of the present application provide a vehicle-mounted device, a display device, an audio device and a terminal, which can significantly improve the anti-collision performance of the vehicle-mounted device and ensure user safety.

[0073] Please refer to Figure 2 and Figure 3 , Figure 2 is a schematic cross-sectional structure diagram of a vehicle-mounted device provided in an embodiment of the present application, Figure 3 1 is a schematic diagram of a three-dimensional structure of a vehicle-mounted device provided in an embodiment of the present application. The vehicle-mounted device 10 comprises a housing 101 and a panel 102. Among them:

[0074] At least part of the housing 101 surrounds and forms the cavity 30. In other words, the housing 101 may be used as a whole to form the cavity 30, or the housing 101 may include multiple parts, and parts of the housing 101 surround and form the cavity 30. Optionally, the housing 101 may form the bottom wall and the side wall of the cavity 30, or the housing 101 may only be used to form the side wall of the cavity 30.

[0075] The panel 102 is provided with a connection hole 1021. The connection hole 1021 may be a through hole, a semi-through hole, or the like.

[0076] The housing 101 is fixedly assembled with the panel 102 through a first connection structure. The first connection structure may include a pin, a buckle, and other structures capable of achieving a fixed connection. The following description takes the first connection structure being a pin as an example. Figure 2 As shown, the first connection structure can be a pin 1011, one end of the pin 1011 is connected to the housing 101, and the other end is inserted into the connection hole 1021, so that the housing 101 and the panel 102 can be fixedly connected. An adhesive layer 103 is also provided between the housing 101 and the panel 102, and the adhesive layer 103 is used to bond the panel 102 to the housing 101.

[0077] In such Figure 2 In the illustrated embodiment, the adhesive layer 103 and the pins 1011 fix the panel 102 to the housing and can conduct and disperse the impact force on the panel 102 when the panel 102 is impacted. Therefore, the pins 1011 and the adhesive layer 103 can be regarded as the energy absorbing component 20.

[0078] On the one hand, the adhesive layer 103 forms an adhesive interface with the shell 101 and the panel 102 respectively, so that the shell 101 and the panel 102 are tightly connected. When the panel 102 is subjected to external force, the adhesive layer transmits the force of the panel 102 to the shell 101. On the other hand, the assembly between the pin 1011 set on the shell 101 and the connection hole 1021 of the panel 102 can realize the fixed connection between the panel 102 and the shell 101, further ensuring the tight connection between the panel 102 and the shell 101. Figure 2In the vehicle-mounted device 10 shown, when an object hits the panel 102, the impact force is transmitted to the shell 101 and other components through the adhesive layer 103 and the pin 1011 after reaching the panel 102, making it less likely for the panel 102 to be deformed, fall off, break, etc., thereby significantly improving the anti-collision performance of the vehicle-mounted device 10 and ensuring user safety.

[0079] In one embodiment, the first connection structure can be fixedly disposed on the housing 101. Taking the pin 1011 as an example, the pin 1011 can be disposed on the housing 101, one end of the pin 1011 can be connected to the housing (the connection here can include the case where the pin 1011 and the housing 101 are integrally connected), and the other end is a free end for fixed assembly with the panel 102. In some schemes, the housing 101 includes an integral middle shell, and the pin can be integrally connected to the middle shell, that is, the housing 101 has the pin 1011. In some schemes, the housing 101 includes a plurality of components that are separately disposed (described below), and the pin 1011 can be integrally connected to a portion (e.g., one of) of the components in the housing 101, that is, the portion of the components included in the housing 101 has the pin 1011.

[0080] In one embodiment, the energy absorbing assembly 20 is disposed at the edge of the panel 102, such as Figure 2 shown.

[0081] In one embodiment, the panel 102 is used to seal the cavity 30. The sealing here can be fully sealed or semi-sealed. In this embodiment, since there is a cavity 30 in the shell 101, when the panel 102 is hit by an external force, it will be recessed into the cavity in the shell 101, and the energy absorbing component 20 can fasten the panel 102 to resist the impact force, thereby improving the anti-collision performance of the overall structure.

[0082] In one embodiment, the panel 102 includes a glass panel. Optionally, the thickness of the panel 102 is greater than or equal to 4 millimeters (mm), for example, the thickness of the panel is 4.1 mm. When the thickness of the panel is greater than 4 mm, the panel 102 can have a greater stress when being impacted by an object to resist deformation caused by the impact, so that the vehicle-mounted device can have a stronger anti-collision performance.

[0083] In some embodiments, the panel 102 comprises a composite glass panel, comprising at least two layers stacked. As a possible implementation, the panel 102 comprises an inorganic material layer and an organic material layer stacked. In some cases, the thickness of the inorganic material layer is greater than or equal to 2 mm, and the thickness of the organic material layer is greater than or equal to 2 mm.

[0084] Optionally, the panel 102 may have multiple connection holes 1021, and accordingly, the housing 101 may also have multiple pins 1011 that are connected to the connection holes 1021. Multiple connection holes 1021 may be provided at a portion close to the edge of the panel 102. In some embodiments, the connection holes 1021 may be provided around the edge of the panel 102. Figure 3 When the panel 102 is a polygon, the connection hole 1021 can be set at a corner of the panel close to the polygon, which is more conducive to fixing the panel 102 in combination with the energy absorbing component 20.

[0085] In one embodiment, the adhesive layer 103 includes a flexible member with viscosity. In some schemes, the adhesive layer 103 includes a glue layer and a buffer layer, the glue layer is sticky and can achieve connection between objects, and the buffer layer is used to achieve buffering to enhance the stability of the overall structure. Exemplarily, the adhesive layer 103 can be implemented by glue, in which case the surface layer of the glue is sticky, and the middle part of the glue can serve as a buffer layer to play a buffering role. Another exemplary embodiment, the adhesive layer 103 can be a double-backed foam, which includes two layers of glue stacked and a foam layer located between the two sides of the glue, wherein the two layers of glue can form a bonding interface between the shell and the panel, and the foam layer can play a buffering role to enhance the stability and anti-collision performance of the vehicle-mounted device.

[0086] Optionally, the adhesive layer 103 may be Figure 3 The multiple parts shown include separate arrangements. Of course, the present application is also applicable to the adhesive layer 103 of one-piece design.

[0087] Optionally, the adhesive layer 103 may be provided between the housing 101 (or the main body of the housing) and the panel. Furthermore, the gap between the pin 1011 and the panel 102 may also be filled with an adhesive material, thereby further improving the stability of the pin and the connection hole assembly, and the adhesive material may also be regarded as the adhesive layer 103.

[0088] Alternatively, the pin 1011 described in various embodiments of the present application may also be replaced by other connection structures capable of fixing the connection between the panel 102 and the housing 101 .

[0089] The possible designs of the housing 101 are introduced below.

[0090] In one embodiment, combining Figure 2 and Figure 3 The housing 101 is an integrated structure. The main body of the housing 101 is used to enclose the cavity 30. The housing 101 also has a pin 1011. The pin 1011 of the housing 101 is assembled with the connecting hole 1021 of the panel 102 to achieve a fixed connection between the housing 101 and the panel 102. Figure 2In the structure shown, when the impact force reaches the panel 102, the force on the panel 102 can be transmitted to the shell 101 by the energy absorbing component 20, and the connection between the panel 102 and the shell 101 is made more stable, thereby improving the anti-collision capability of the overall structure. In short, the shell 101 not only forms a cavity, but also stabilizes and fixes the panel 102, and does not introduce other structural parts, so that the anti-collision requirements can be met at a reduced cost.

[0091] See also Figure 4 Especially when the impact point of the impact object on the vehicle-mounted device is located near the position of the energy absorbing component on the panel, the housing 101 can also provide support for the panel, further improving the anti-collision performance of the vehicle-mounted device. Figure 1 For example, when the vehicle-mounted device is installed near the roof of the vehicle, such as the headrest of the seat, the upper part of the vehicle body, etc., the impact of the object on the vehicle-mounted device is usually located at the lower part of the vehicle-mounted device. Therefore, for the components at these locations, Figure 4 The vehicle-mounted device shown can improve the anti-collision capability of the vehicle-mounted device at a relatively favorable cost.

[0092] certainly, Figure 3 The illustrated embodiment is merely an example, and possible designs of the position and function of the housing 101 will be described below.

[0093] In one embodiment, please refer to Figure 5 and Figure 6 The housing 101 includes a middle shell 1012 and a structural member 1013. The panel 102 is fixedly mounted on the structural member 1013 through the energy absorbing assembly 20. The pin 1011 is arranged on the side of the structural member 1013 facing the panel 102, and the adhesive layer 103 is arranged between the panel 102 and the structural member 1013. The detailed description of some components can be found in the above text.

[0094] In other words, the structural member 1013 is separately arranged from the middle shell 1012, and the middle shell 1012 is enclosed to form a cavity 30. The structural member 1013 is used to fix and prevent collisions of the panel, thereby realizing the decoupling of different functional components. For example, since the structural member is subjected to force, a material with greater rigidity (such as a metal material) or a more stable structure (such as an arch) can be used, thereby improving the stability of the overall mechanism, and since the middle shell 1012 is mainly used to form a cavity, other materials can be used, such as a more soundproof, or more heat-insulating, or lighter material, such as a plastic material. It is not difficult to see that when the impact force reaches the panel 102, the force exerted on the panel 102 can be transmitted to the structural member 1013 by the energy-absorbing component 20, and can further be transmitted to other devices through the structural member 1013, so that the installation of the panel 102 is more stable, and the anti-collision ability of the vehicle-mounted device 10 is improved.

[0095] exist Figure 5 and Figure 6 In the structure shown, the structural member 1013 is located between the middle shell 1012 and the panel 102. When the panel 102 is hit and generates an impact force in the direction of the cavity, the adhesive layer 103 and the pins 1011 on the structural member 1013 can fix the panel, and the structural member 1013 can also provide support to the panel 102, further improving the anti-collision performance of the vehicle-mounted device. In particular, when the impact point is located near the position of the energy absorbing component on the panel, the panel 102 is not easy to deform, and the structural member 1013 can firmly support the panel 102, so that the overall structure is stable and has excellent anti-collision performance.

[0096] For example, the middle shell 1012 may abut against the structural member 1013. In this way, the structural member 1013 may transmit the impact force or part of the impact force to the middle shell 1012, thereby achieving force transfer and dispersion and improving the overall structural stability.

[0097] In one embodiment, when the structural member 1013 is separately provided from the middle shell 1012, the structural member 1013 can be fixedly connected to the middle shell 1012. This can further improve the stability of the overall structure formed by the energy absorbing component, the panel and the shell, and further improve the anti-collision performance. In some possible implementations, the fixed connection can be achieved by one or more devices such as pins, screws, buckles, etc.

[0098] See also Figure 7 The structural member 1013 and the middle shell 1012 can be fixedly connected by self-tapping screws 104. Figure 8 The structural member 1013 is provided with a through hole 1017 , and the middle shell 1012 is provided with a blind hole 1016 . The self-tapping screw 104 can pass through the through hole 1017 and be inserted into the blind hole 1016 , thereby achieving a fixed connection between the structural member 1013 and the middle shell 1012 .

[0099] In some embodiments, see Figure 7 , a groove 1014 is also provided on one side of the middle shell 1012 close to the panel 102, and a flexible material 105 can be provided in the groove 1014. Generally speaking, under natural conditions, the thickness of the flexible material 105 is higher than the depth of the groove 1014, and one end of the flexible material 105 abuts against the bottom surface of the groove 1014, and the other end abuts against the structural member 1013. In this way, a dustproof or soundproof design of the vehicle-mounted device can be achieved, and the service life and service quality of the device can be improved. For example, if a flexible material 105 is provided, dust can be prevented from entering the cavity 30 through the gap between the middle shell 1012 and the structural member 1013. On the other hand, the flexible material 105 can also play a buffering role, further improving the stability of the overall structure. Optionally, the flexible material can be, for example, foam (such as sponge).

[0100] In some embodiments, see Figure 7 The structural member 1013 is provided with a protrusion 1015, which extends from the structural member 1013 to the panel 102, and the top of the protrusion 1015 abuts the panel 102. The adhesive layer 103 is provided on the side of the protrusion 1015 away from the center of the panel 102. Considering a possible situation, if the central part of the panel 102 is hit, since the panel 102 will be deformed into the cavity 30 when hit, the adhesive layer 103 will be subjected to a pulling force in the direction of the impact point. When the pulling force acts on the adhesive layer 103, the adhesive layer will have a tendency to move toward the impact point. By providing the protrusion 1015, a supporting force away from the impact point can be provided for the adhesive layer 103, so that the adhesive layer 103 is not easy to deform and displace. On the one hand, the stability of the overall structure can be further improved, and the anti-collision performance of the device can be improved. On the other hand, the adhesive layer 103 is not easy to be debonded, and the overall aesthetics can be improved.

[0101] Optionally, considering that the housing 101 is an integrated design, the protrusion 1015 may also be a protrusion of the housing 101 toward the panel 102. Figure 7 Description of protrusion 1015 in .

[0102] It should be understood that the aforementioned Figures 2 to 8 The description is made by taking the example that the structural member 1013 is arranged on the side of the panel 102 close to the cavity 30. In actual implementation, the positional relationship between the structural member 1013 and the panel 102 may have other designs.

[0103] In another embodiment, the housing 101 includes a middle shell 1012 and a structural member 1013, and at least a portion of the structural member 1013 is disposed on a side of the panel 102 away from the cavity 30. Fig. 9 The shell 101 includes a middle shell 101 and a structural member 1013. The panel 102 is fixedly mounted on the structural member 1013 through the energy absorbing assembly 20. The pin 1011 is arranged on the side of the structural member 1013 facing the panel 102, and the adhesive layer 103 is arranged between the panel 102 and the structural member 1013. Since the structural member 1013 is arranged on the side of the panel 102 away from the cavity 30, when an object hits the panel 102, the impact force is transmitted to the structural member 1013 and other components through the adhesive layer 103 and the pin 1011 after reaching the panel 102, which is equivalent to the structural member 1013 providing "pulling force" for the panel, making it less likely for the panel 102 to be deformed, fall off, break, etc., thereby improving the anti-collision performance of the vehicle-mounted device 10 and ensuring user safety.

[0104] Combination Fig. 9As in the above-mentioned embodiment, in a possible implementation, the middle shell 1012 surrounds and forms the cavity 30. At this time, the middle shell 1012 can abut against the panel 102, so as to provide support for the panel 102 when an external force acts on the panel 102, thereby further fixing the panel 102 to prevent it from falling off and deforming, and significantly improving the anti-collision capability of the overall structure.

[0105] In another embodiment, please refer to Fig.10 Part (a) and Fig.10 Part (b) of Fig.10 Part (b) of Fig.10 The enlarged schematic diagram of the structure of part (a) shows that the structural member 1013 includes a bottom plate 1017 and a side wall 1018. The side wall 1018 of the structural member 1013 is arranged around the bottom plate 1017. The bottom plate 1017 is annularly covered on the edge of the panel 102. The side of the bottom plate 1017 facing the panel 102 is provided with a pin 1011, and the side wall 1018 is arranged around the periphery of the middle shell 1012. In this way, when an impact object hits the side wall and panel of the structural member, the impact force generated by the impact can be timely transmitted by the structural member, the shell, etc., thereby improving the anti-collision capability of the overall structure.

[0106] See also Fig.11 , Fig.11 1 is a schematic diagram of a three-dimensional structure of another vehicle-mounted device 10 provided in an embodiment of the present application. The vehicle-mounted device 10 includes a middle shell 1012, a structural member 1013, a rear shell 1019 and a panel 102. The middle shell 1012 and the rear shell 1019 together form a cavity 30. The panel 102 is covered on the cavity 30 to close the cavity 30. The panel 102 is provided with an energy absorbing component ( Fig.11 The middle shell 1012 is fixedly mounted on the structural member 1013 (not shown). The structural member 1013 also includes a side wall arranged around the periphery of the middle shell 1012. When an impacting object hits the side wall and panel of the structural member, the impact force generated by the impact can be timely transmitted to the structural member, the outer shell, etc., thereby improving the anti-collision capability of the overall structure.

[0107] In another embodiment, continue to refer to Fig.10, a groove 1014 is also provided on one side of the middle shell 1012 close to the panel 102, and a flexible material 105 can be provided in the groove 1014. Under natural circumstances, the thickness of the flexible material 105 is higher than the depth of the groove. Furthermore, the position of the groove 1014 is opposite to the position of the connecting hole 1021 in the panel 102, and the opening size of the groove 1014 is larger than the size of the connecting hole 1021. It is understandable that due to the design of the connecting hole, external dust may enter the cavity 30 through the connecting hole. By providing the groove 1014 and providing the flexible material 105 in the groove 1014, a dustproof design or a soundproof design can be achieved, thereby improving the service life and service quality of the device. On the other hand, the flexible material 105 can play a buffering role, further improving the stability of the overall structure. Optionally, the flexible material can be, for example, foam (such as sponge).

[0108] In one embodiment, the structural member 1013 is a metal member. For example, the material of the structural member 1013 may be pure metal, alloy, or a combination of pure metal and alloy, etc. Optionally, the structural member may be a one-piece material, or may include multiple parts that are separately arranged.

[0109] In some cases, the vehicle-mounted device 10 is installed in the seat of a movable terminal, and the movable terminal includes but is not limited to vehicles, logistics robots, aircraft, ships and other terminals. This application takes the vehicle as an example of a movable terminal. The device installed in the vehicle includes but is not limited to a projection device, or a stereo, etc.

[0110] The following describes possible installation methods of the vehicle-mounted device 10 and the mobile terminal. Fig.12 , Fig.12 Schematic diagram of several possible seats with vehicle-mounted devices provided in embodiments of the present application.

[0111] For an example, see Fig.12 In part (a), the seat includes a headrest, and the vehicle-mounted device 10 is disposed on the headrest of the seat. In a possible implementation, since the impact object is more likely to hit the edge of the vehicle-mounted device 10 in the headrest, when the vehicle-mounted device 10 is disposed on the headrest of the seat, it can be used Figure 3 , Figure 4 The structure shown is implemented to achieve anti-collision performance that meets user needs at a relatively low cost.

[0112] For an example, see Fig.12 In part (b), the seat includes a headrest, and the vehicle-mounted device 10 is arranged on the backrest of the seat.

[0113] Optionally, the headrest and backrest of the seat can be provided separately or in one piece.

[0114] For an example, see Fig.12 In part (c), the seat includes a headrest, a backrest, and a connecting portion connecting the backrest and the headrest, and the vehicle-mounted device 10 is arranged at the connecting portion.

[0115] In some cases, the vehicle-mounted device 10 may be fixedly assembled with a seat. Several possible implementations of the fixed assembly are described below.

[0116] In one embodiment, the vehicle-mounted device 10 includes a housing 101, and the housing 101 is fixedly connected to the seat. Two possible connection methods are exemplarily described below:

[0117] Example 1: The vehicle-mounted device includes a structural member 1013, and the structural member 1013 is fixedly connected to the seat. In this way, on the one hand, the stability of the overall structure can be improved, and on the other hand, the force transmitted to the structural member can be directly transmitted to the seat through the fixed connection, and the seat can provide a fixing and buffering effect for the vehicle-mounted device, further improving the anti-collision ability of the vehicle-mounted device.

[0118] Exemplarily, the structural member 1013 may be fixedly assembled with the seat by means of buckles, screws, pins, etc. In some embodiments, when the vehicle-mounted device 10 is disposed in a headrest of the seat, the structural member 1013 is fixedly connected to the outer shell of the headrest.

[0119] Example 2: The vehicle-mounted device 10 further includes a fixed connection structure 106, which is used to fixedly connect the housing 101 and the seat. Fig.13 , Fig.13 1 is a schematic diagram of the overall structure of a vehicle-mounted device provided in an embodiment of the present application, wherein the fixed connection structure 106 comprises a rotating shaft fixing member 1061 and a rotating shaft cantilever 1062, wherein: the rotating shaft fixing member 1061 is fixedly connected to the middle shell 1012, the rotating shaft fixing member 1061 has a protruding rotating shaft 1063, and the rotating shaft cantilever 1062 is provided with a rotating shaft connection hole (not shown in the figure), and the rotating shaft connection hole is used to assemble with the rotating shaft 1063 to realize the rotation of the rotating shaft cantilever 1062 around the rotating shaft 1063. Furthermore, the rotating shaft cantilever 1062 comprises a second connection structure, and the second connection structure is used to realize the fixed connection between the rotating shaft cantilever 1062 and the seat. For example, a through hole is also provided on the rotating shaft cantilever 1062, and screws, pins, etc. can be passed through the through hole to assemble with the seat to realize the fixed connection between the rotating shaft cantilever 1062 and the seat. Alternatively, a buckle component is provided on the rotating shaft cantilever, and a connecting component coupled to the buckle component is provided on the seat, and a fixed connection between the rotating shaft cantilever 1062 and the seat can be achieved by assembling the buckle component and the connecting component.

[0120] In the above embodiment, the impact force can be quickly transferred to the seat by means of a rotating shaft cantilever and a rotating shaft, thereby improving the stability of the vehicle-mounted device when subjected to external forces (such as vibrations, collisions, etc.). In addition, the rotating shaft cantilever is combined with the fixed rotating shaft structure to further improve the stability and anti-collision capability of the vehicle-mounted device.

[0121] It should be understood that the above two examples can also be combined, for example, fixedly connected to the seat through the structural member 1013 and fixedly connected to the seat through the fixed connection structure 106 arranged on the middle shell 1012.

[0122] Optionally, one end of the shaft fixing member 1061 may also be connected to the structural member 1013, so that the impact force can be transmitted to the shaft fixing member 1061 through the structural member 1013 and further transmitted to the seat through the shaft cantilever 1062. The connection here may include fixed connection, abutment and other connection methods.

[0123] In some cases, the vehicle-mounted device 10 may also include a signal source, which is located in the cavity. The signal source is used to generate a signal, and the signal is transmitted to the object space through the cavity and the panel. Among them, the signal includes but is not limited to signals such as light, sound waves, and electromagnetic waves. It is not difficult to see that the cavity of the vehicle-mounted device can form the function of the signal conduction path to complete its specific function. Exemplarily, when the signal is light, a variety of optical elements can be arranged in the cavity, and the light can produce reflection, refraction and other phenomena in the optical elements in the cavity, and the cavity can not only provide space for the path design of the light, but also achieve the effect of water release and dust prevention, thereby improving the service life of the vehicle-mounted device. As another example, when the signal is a sound wave, the multiple reflections of the sound wave by the cavity can improve the playback effect and enhance the user experience.

Further, the transmission can be used to generate a virtual image visible to the human eye.

[0127] Optionally, the display device is installed in the mobile terminal, for example, in a seat of the mobile terminal.

[0128] In some possible implementations, the display device further includes an optical element, which is disposed in the cavity and is used to process the light beam. The processing here includes propagation and changes to the characteristics of the light beam during the propagation process. Among them, propagation can include one or more of the propagation processes such as transmission, refraction, or reflection, and the change to the characteristics of the light beam includes one or more of the changes to the optical path of the light beam (such as deflection, reflection, etc.), the change of the polarization direction of the light contained in the emitted light beam, the change of the wavelength distribution (such as filtering), etc.
