DETAILED DESCRIPTION

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0047] like Figures 1 to 10 As shown, the projection assembly includes: housing 10, bottom cover 20, display module 30, heat dissipation assembly 40, and imaging lens 50.

[0048] The housing 10 is connected to the bottom cover 20, and the housing 10 and the bottom cover 20 form a receiving space. The heat dissipation assembly 40, the display module 30, and the imaging lens 50 are all disposed in the receiving space, and the display module 30 is disposed on the heat dissipation assembly 40. The imaging lens 50 includes a lens barrel 51 and a lens assembly 52. ​​The lens barrel 51 is disposed on the heat dissipation assembly 40, and the lens assembly 52 is disposed in the lens barrel 51. The lens barrel 51 surrounds the display module 30, and the display module 30 faces the lens assembly 52. ​​An opening is provided on the housing 10, and the lens assembly 52 faces the opening.

[0049] In the embodiment of the present application, since the shell 10 is connected with the bottom cover 20, and the shell 10 and the bottom cover 20 form a containing space, the heat dissipation assembly 40, the display module 30 and the imaging lens 50 can be arranged in the containing space. Since the display module 30 is arranged on the heat dissipation assembly 40, the imaging lens 50 includes a lens barrel 51 and a lens assembly 52, the lens barrel 51 is arranged on the heat dissipation assembly 40, the lens is arranged in the lens barrel 51, the lens barrel 51 surrounds the display module 30, and the display module 30 faces the lens assembly 52, so that when the display module 30 displays an image, the light emitted by the display module 30 can pass through the lens assembly 52, be imaged by the lens assembly 52, and the heat emitted by the display module 30 can be dissipated by the heat dissipation assembly 40. Since the shell 10 is provided with an opening, and the lens assembly 52 faces the opening, when the lens assembly 52 images, the light emitted by the display module 30 can pass through the lens assembly 52 and then pass out of the opening of the shell 10, so that the lens assembly 52 can image outside the shell 10, and when the projection assembly is applied to a vehicle, the light emitted by the display module 30 can be displayed on a to-be-displayed device in the vehicle after passing through the lens assembly 52, so that the driver can see the image displayed by the display module 30 on the to-be-displayed device. That is, in the embodiment of the present application, by arranging the heat dissipation assembly 40, the display module 30 and the imaging lens 50 in the containing space formed by the shell 10 and the bottom cover 20, when the display module 30 displays an image, the image displayed by the display module 30 can be imaged by the imaging lens 50, and the image can be transmitted to the outside of the shell 10 through the opening on the shell 10, and the heat dissipation assembly 40 can dissipate heat of the display module 30, so that in the imaging projection process of the projection assembly, the heat emitted by the projection assembly can be dissipated by the heat dissipation assembly 40, so that the projection effect of the projection assembly is better.

[0050] It should be noted that in the embodiment of the present application, the lens assembly 52 can include at least one lens, for example, the lens assembly 52 includes two lenses. When the lens assembly 52 includes multiple lenses, at this time, the multiple lenses can include convex lenses and concave lenses, and the specific arrangement of the convex lenses and the concave lenses can be set according to actual needs, and the embodiment of the present application does not limit this.

[0051] In addition, in the embodiment of the present application, the lens barrel 51 can include a plurality of sub-barrels which are sleeved with each other, for example, the lens barrel 51 includes two sub-barrels which are sleeved, i.e., one sub-barrel is sleeved on the other sub-barrel, and the two sub-barrels are bonded by the bonding glue 001. When the lens barrel 51 includes two sub-barrels which are sleeved, at this time, the sub-barrel located on the inside of the lens barrel 51 can be a plastic structure, and the sub-barrel located on the outside of the lens barrel 51 can be a metal material or a plastic material. When the sub-barrel located on the inside of the lens barrel 51 is a plastic material, at this time, the sub-barrel can surround the display module 30 and play a protective role for the display module 30. In addition, it can also facilitate the processing of the sub-barrel on the outside of the lens barrel 51. Of course, the lens barrel 51 can also include other numbers of sub-barrels, for example, the lens barrel 51 includes three sub-barrels which are sleeved with each other. The number of sub-barrels included in the lens barrel 51 is not limited in the embodiment of the present application.

[0052] In addition, in the embodiment of the present application, the diameter of the lens barrel 51 can be made larger, i.e., the lens barrel 51 can have a larger space at the display module 30 so as to avoid that the light emitted by the display module 30 is irradiated on the inner wall of the lens barrel 51 after the lens barrel 51 surrounds the display module 30, thereby affecting the imaging effect of the display module 30 through the lens assembly 52.

[0053] In addition, in some embodiments, as shown in Figure 3 and Figure 10 It can be seen that a plurality of first air holes 21 can be arranged on the bottom cover 20, and the heat dissipation assembly 40 can include a heat conduction block 41 and a plurality of heat dissipation fins 42. The heat conduction block 41 includes opposite first and second faces, the second face faces the plurality of first air holes 21 on the bottom cover 20, and the display module 30 is arranged on the first face, and the plurality of heat dissipation fins 42 are arranged on the second face.

[0054] Since the heat dissipation assembly 40 includes the heat conduction block 41 and the plurality of heat dissipation fins 42, the display module 30 is arranged on the first face of the heat conduction block 41, and the plurality of heat dissipation fins 42 are arranged on the second face, therefore, when the display module 30 dissipates heat, the heat conduction block 41 can conduct the heat dissipated by the display module 30 to the plurality of heat dissipation fins 42. Since the plurality of first air holes 21 are arranged on the bottom cover 20, and the second face faces the plurality of first air holes 21 on the bottom cover 20, i.e., the plurality of heat dissipation fins 42 face the plurality of first air holes 21, therefore, when the heat conduction block 41 conducts heat to the plurality of heat dissipation fins 42, the plurality of heat dissipation fins 42 can transmit the heat to the outside of the shell 10 through the plurality of first air holes 21, so that the heat generated by the display module 30 can be transmitted to the outside of the shell 10.

[0055] It should be noted that, in this embodiment of the invention, the material of the heat-conducting block 41 can be a material that easily conducts heat. For example, the material of the heat-conducting block 41 is aluminum, or it can be copper. This embodiment of the invention does not limit the material of the heat-conducting block 41.

[0056] Furthermore, in this embodiment of the invention, the shape of the heat dissipation fins 42 can be set according to actual needs. For example, the heat dissipation fins 42 can be rectangular or wavy. The specific shape of the heat dissipation fins 42 is not limited in this embodiment. Additionally, in this embodiment, the material of the heat dissipation fins 42 can be a material that facilitates heat dissipation. For example, the material of the heat dissipation fins 42 can be copper or silver. The material of the heat dissipation fins 42 is not limited in this embodiment.

[0057] Additionally, in some embodiments, such as Figure 3 As shown, the heat dissipation assembly 40 may further include a cooling fan 43. The housing 10 has multiple second vents 11, all facing the fins. The cooling fan 43 is located on the second side, with multiple heat dissipation fins 42 surrounding it. The cooling fan 43 faces the bottom cover 20, allowing the airflow generated by the cooling fan 43 to pass through the first vent 21 or the second vent 11.

[0058] When the heat dissipation assembly 40 includes a cooling fan 43, and the cooling fan 43 is disposed on the second side, with multiple heat dissipation fins 42 surrounding the cooling fan 43, the cooling fan 43 can rotate to generate airflow when the heat dissipation block 41 conducts the heat emitted by the display module 30 to the multiple heat dissipation fins 42. Since the housing 10 is provided with multiple second air holes 11 facing the heat dissipation fins 42, and the cooling fan 43 faces the bottom cover 20, i.e., the cooling fan 43 faces the multiple first air holes 21, when the cooling fan 43 rotates, air from outside the housing 10 can enter the interior of the housing 10 through the first air holes 21 or the second air holes 11, i.e., enter the receiving space, so that the cooling fan 43 can generate airflow. This airflow flows through the second air holes 11 or the first air holes 21, i.e., flows to the outside of the housing 10 through the second air holes 11 or the first air holes 21, thereby transferring the heat generated by the display module 30 to the outside of the housing 10. In other words, by setting up the cooling fan 43, airflow can be generated in the housing space to accelerate the heat dissipation efficiency of the display module 30.

[0059] It should be noted that in this embodiment of the invention, the cooling fan 43 can be an axial fan, or it can be a radial fan. When the cooling fan 43 is an axial fan, the first air hole 21 on the housing 10 is equivalent to an air inlet, and the second air hole 11 on the bottom cover 20 is equivalent to a heat dissipation hole. During operation, the airflow enters the receiving space through the first air hole 21 and then exits through the second air hole 11, thus forming a cooling airflow that carries the heat emitted by the display module 30 out of the external space of the housing 10. When the cooling fan 43 is a radial fan, the first air hole 21 on the housing 10 is equivalent to a heat dissipation hole, and the second air hole 11 on the bottom cover 20 is equivalent to an air inlet. During operation, the airflow enters the receiving space through the second air hole 11 and then exits through the first air hole 21, thus forming a cooling airflow that carries the heat emitted by the display module 30 out of the external space of the housing 10. The specific type of cooling fan 43 is not limited in this embodiment of the invention.

[0060] Additionally, in some embodiments, such as Figure 3 As shown, the projection assembly may also include a control circuit 60. The control circuit 60 is disposed in the receiving space, and the display module 30 is electrically connected to the control circuit 60. The control circuit 60 is used to control the display module 30 to display.

[0061] When the projection assembly includes the control circuit 60, and the display module 30 is electrically connected to the control circuit 60, the control circuit 60 can send a control signal to the display module 30, causing the display module 30 to display based on the control signal. In other words, by setting the control circuit 60, the display of the display module 30 can be easily controlled.

[0062] It should be noted that the control circuit 60 can be integrated on a printed circuit board (PCB), or it can be integrated on a flexible printed circuit (FPC). This embodiment of the invention does not limit the specific integration of the control circuit 60.

[0063] Additionally, when the projection assembly includes a cooling fan 43, the cooling fan 43 can be electrically connected to the control circuit 60, allowing the control circuit 60 to control the cooling fan 43. Furthermore, in this embodiment, when the control circuit 60 is integrated on a printed circuit board, a battery can also be mounted on the printed circuit board and connected to the cooling fan 43 to supply power to it.

[0064] Additionally, in some embodiments, such as Figure 3 As shown, the projection assembly may also include a fixture 70. The fixture 70 is disposed in the receiving space, and the control circuit 60 is connected to the fixture 70. The fixture 70 is used to fix the control circuit 60.

[0065] When the projection assembly includes a fixing member 70 and the control circuit 60 is connected to the fixing member 70, the fixing member 70 can fix the control circuit 60 in the receiving space. That is, the fixing member 70 fixes the position of the control circuit 60 in the receiving space, thus avoiding the problem of the control circuit 60 shaking in the receiving space.

[0066] When the control circuit 60 is integrated on the printed circuit board, the printed circuit board is connected to the fixing member 70, and the fixing member 70 fixes the printed circuit board in the receiving space.

[0067] It should be noted that the fastener 70 can be fixedly connected to the inner wall of the housing 10, thereby fixing its position in the receiving space and thus fixing the position of the control circuit 60 in the receiving space. Furthermore, the fastener 70 can be made of plastic or metal; this embodiment of the invention does not limit its material.

[0068] Additionally, in some embodiments, such as Figure 3 As shown, the projection assembly may also include an interface assembly 80. A through-hole is provided on the housing 10, with part of the interface assembly 80 located within the receiving space and part of the connector assembly located within the through-hole. The interface assembly 80 is electrically connected to the control circuit 60.

[0069] When the projection component includes an interface component 80, and the interface component 80 is electrically connected to the control circuit 60, data can be transmitted to the control circuit 60 through the interface component 80, or electrical power can be supplied to the control circuit 60 through the interface component 80, thereby facilitating the use of the projection component. In other words, by setting up the interface component 80, the use of the projection component can be made easier.

[0070] It should be noted that the interface component 80 can be a Type-C interface, but it can also be other types of interfaces; this embodiment of the invention does not limit the specific type. Furthermore, in this embodiment, the interface component 80 can be electrically connected to the control circuit 60 via a connecting cable.

[0071] Additionally, in some embodiments, such as Figure 1 and Figure 4 As shown, the projection assembly may further include a rotation adjustment assembly 90. The rotation adjustment assembly 90 includes a mounting housing 91 and a movable connector 92. The mounting housing 91 has a receiving cavity, a first end of the movable connector 92 is disposed in the receiving cavity and is movable within the receiving cavity, and a second end of the movable connector 92 is connected to the housing 10. The movable connector 92 is used to adjust the angle of the housing 10 relative to the rotation adjustment assembly 90. The first end and the second end are opposite each other.

[0072] Since the first end of the movable connector 92 is located in the receiving cavity of the mounting shell 91 and is movable in the receiving cavity, and the second end of the movable connector 92 is connected to the shell 10, when it is necessary to adjust the angle of the shell 10 relative to the rotation adjustment component 90, an external force can be applied to the shell 10, causing the shell 10 to drive the second end of the movable connector 92 to move, thereby causing the first end of the movable connector 92 to rotate in the receiving cavity, thereby causing the angle of the shell 10 relative to the rotation adjustment component 90 to change, and causing the angle of the display module 30 in the shell 10 relative to the rotation adjustment component 90 to change.

[0073] It should be noted that, in this embodiment of the invention, the first end of the movable connector 92 can be spherical, and the second end of the movable connector 92 can be rod-shaped. In this case, the spherical first end can rotate within the receiving cavity of the mounting shell 91. That is, when it is necessary to adjust the angle of the shell 10 relative to the rotation adjustment component 90, the shell 10 can be rotated, thereby causing the shell 10 to move the second end of the movable connector 92, thus allowing the spherical first end to rotate within the receiving cavity, causing the angle of the shell 10 relative to the rotation adjustment component 90 to change. Furthermore, the spherical shape of the first end of the movable connector 92, when rotating within the receiving cavity, allows the movable connector 92 to have three degrees of freedom, thereby allowing the shell 10 to have three degrees of freedom relative to the rotation adjustment component 90.

[0074] In addition, in this embodiment of the invention, when the projection component is applied in a vehicle, in order to prevent the connection between the second end of the movable connector 92 and the housing 10 from becoming loose due to vehicle vibration during driving, adhesive 001 can be provided at the connection between the second end of the movable connector 92 and the housing 10 to seal the gap between the second end of the movable connector 92 and the housing 10.

[0075] In addition, in this embodiment of the invention, a threaded hole may be provided on the housing 10, and a thread may be provided on the second end of the movable connector 92, so that the movable connector 92 can be embedded in the threaded hole, thereby connecting the movable connector 92 to the housing 10.

[0076] Additionally, in some embodiments, such as Figure 4 As shown, a fastening adjustment member 93 may be provided on the mounting housing 91. When the angle between the housing 10 and the rotation adjustment assembly 90 is determined, the fastening adjustment member 93 abuts against the first end of the movable connector 92 to fix the position of the first end of the movable connector 92 in the receiving cavity.

[0077] When a fastening adjustment member is provided on the mounting housing 91, when it is necessary to adjust the angle of the housing 10 relative to the rotation adjustment assembly 90, the housing 10 can drive the movable connecting member 92 to move, so that the first end of the movable connecting member 92 rotates in the receiving cavity. When the angle of the housing 10 relative to the rotation adjustment assembly 90 is determined, the fastening adjustment member 93 can abut against the first end of the movable connecting member 92, so that the first end of the movable connecting member 92 cannot rotate in the receiving cavity, thereby fixing the position of the movable connecting member 92 in the receiving cavity, and thus fixing the angle of the housing 10 relative to the rotation adjustment assembly 90. That is, by providing the fastening adjustment member 93, the position of the housing 10 can be fixed when the angle of the housing 10 relative to the rotation adjustment assembly 90 is determined.

[0078] It should be noted that, in this embodiment of the invention, the fastening adjustment member 93 can fasten the screw. When the housing 10 is rotated to determine the angle between the housing 10 and the rotation adjustment component 90, the fastening screw can be rotated to abut against the first end of the movable connector 92. This prevents the first end of the movable connector 92 from rotating relative to the receiving cavity of the mounting housing 91, thus fixing the position of the movable connector 92 and the position of the housing 10. In other words, the angle between the housing 10 and the rotation adjustment component 90 no longer changes. When it is necessary to readjust the angle between the housing 10 and the rotation adjustment component 90, the fastening screw can be rotated again to remove the fastening screw from abutting the first end of the movable connector 92. This allows the first end of the movable connector 92 to rotate relative to the receiving cavity of the mounting housing 91, thereby adjusting the angle of the housing 10 relative to the rotation adjustment component 90. It should be noted that adjusting the angle of the housing 10 relative to the rotation adjustment component 90 is essentially adjusting the angle of the display module 30 relative to the rotation adjustment component 90.

[0079] Additionally, in some embodiments, such as Figure 1 As shown, the projection assembly may also include a mounting bracket 100, and the mounting housing 91 may include a movable part 911 and a connecting part 912, with the movable part 911 connected to the connecting part 912. The movable part 911 is provided with a receiving cavity, and the mounting bracket 100 and the connecting part 912 are detachably connected. The mounting bracket 100 is used to mount the mounting housing 91 on a vehicle.

[0080] Since the mounting bracket 100 and the mounting housing 91 are detachably connected at the connection portion 912, when the mounting housing 91 needs to be replaced, the mounting housing 91 can be removed from the mounting bracket to replace it, and then the replaced mounting housing 91 can be connected to the mounting bracket 100. Furthermore, the mounting bracket 100 can be fixed in a vehicle, allowing the mounting housing 91 to be installed in the vehicle, thus enabling the projection component to be installed in the vehicle.

[0081] It should be noted that, in this embodiment of the invention, the mounting bracket 100 can be connected to the connecting part 912 of the mounting shell 91 by bolts. That is, the movable part 911 is provided with a threaded hole, and the mounting bracket 100 is provided with a through hole. After the bolt passes through the through hole on the mounting bracket 100, it is embedded in the threaded hole on the movable part 911, thereby connecting the mounting bracket 100 and the mounting shell 91.

[0082] Furthermore, when mounting the mounting housing 91 onto the vehicle using the mounting bracket 100, to prevent the connection between the mounting bracket 100 and the mounting housing 91 from loosening due to vehicle vibration during operation, adhesive 001 can be applied to the connection between the mounting bracket 100 and the mounting housing 91 body 10. The adhesive 001 seals the gap between the mounting bracket 100 and the mounting housing 91 body 10, thus preventing loosening due to vehicle vibration. Additionally, when the mounting bracket 100 and the mounting housing 91 are connected using bolts, adhesive 001 is applied to the gap between them. This adhesive 001 not only seals the gap but also adheres to the bolts, making the connection between the mounting bracket 100 and the mounting housing 91 even more secure.

[0083] Additionally, in some embodiments, such as Figure 1 As shown, the projection assembly may also include a fixed support 110. The fixed support 110 is a plate structure and includes a first surface and a second surface opposite to each other. One end of the mounting bracket 100 is connected to the first surface, and an adhesive is provided on the second surface for bonding the fixed support 110 to the vehicle.

[0084] When the projection assembly includes a fixed support 110, one end of the mounting bracket 100 is connected to the first surface of the fixed support 110, and the second surface of the mounting bracket 100 is provided with an adhesive, then when it is necessary to connect the fixed support 110 to a vehicle so that the projection assembly can be installed in the vehicle, the second surface of the fixed support 110 can be directly bonded to the installation position in the vehicle, and the projection assembly can be installed in the vehicle, making it relatively convenient to install the projection assembly in the vehicle.

[0085] It should be noted that the fixed support 110 may be provided with a notch 1101, so that the fixed support 110 can meet the installation position of different vehicles. In particular, when installing a projection component in a vehicle, the projection component is usually installed on the vehicle's center console. Therefore, providing the notch 1101 on the fixed support 110 allows the fixed support 110 to meet the center console of different vehicles, thus making the projection component universal. Furthermore, the shape and number of the notch 1101 can be set according to actual needs, and this embodiment of the invention does not limit them.

[0086] In addition, in this embodiment of the invention, the mounting bracket 100 can be connected to the fixed support 100 by bolts. Of course, it can also be connected by other means, such as by snap-fit ​​connection. This embodiment of the invention does not limit the connection in this respect.

[0087] In this embodiment of the invention, since the housing 10 is connected to the bottom cover 20, and the housing 10 and the bottom cover 20 form a receiving space, the heat dissipation assembly 40, the display module 30, and the imaging lens 50 can be disposed in the receiving space. Because the display module 30 is disposed on the heat dissipation assembly 40, and the imaging lens 50 includes a lens barrel 51 and a lens assembly 52, with the lens barrel 51 disposed on the heat dissipation assembly 40 and the lens disposed within the lens barrel 51, the lens barrel 51 surrounds the display module 30, and the display module 30 faces the lens assembly 52, the light emitted by the display module 30 can pass through the lens assembly 52 to form an image when the display module 30 displays an image, and the heat dissipated by the display module 30 can be dissipated through the heat dissipation assembly 40. Since the housing 10 has an opening and the lens assembly 52 faces the opening, when the lens assembly 52 forms an image, the light emitted by the display module 30 can pass through the lens assembly 52 and then exit through the opening in the housing 10, so that the lens assembly 52 can form an image outside the housing 10. Therefore, when the projection assembly is applied to a vehicle, the light emitted by the display module 30 passes through the lens assembly 52 and can then be displayed on the device to be displayed in the vehicle, so that the driver can see the image displayed by the display module 30 on the device to be displayed. That is, in this embodiment of the invention, by placing the heat dissipation component 40, the display module 30 and the imaging lens 50 in the accommodating space formed by the housing 10 and the bottom cover 20, when the display module 30 displays an image, the image displayed by the display module 30 can be imaged by the imaging lens 50, and the image formed can be transmitted to the outside of the housing 10 through the opening on the housing 10. In addition, the heat dissipation component 40 can dissipate heat from the display module 30, so that the heat emitted by the projection component can be dissipated through the heat dissipation component 40 during the imaging projection process, so that the projection effect of the projection component is better.

[0088] This invention provides a display system, such as... Figure 11As shown, the display system includes a display screen 120 and a projection component as described in any of the above embodiments. The lens assembly 52 faces the display screen 120.

[0089] Since the lens assembly 52 faces the display screen 120, the display module 30 in the projection assembly displays an image. That is, the display module 30 emits light, which can be imaged by the lens assembly 52 and finally displayed on the display screen 120.

[0090] This invention provides a vehicle that includes the display system described in the above embodiments.
