It should be appreciated that any reference in this specification to “one embodiment” or “an embodiment” means that particular features, structures, or characteristics described in connection with the embodiment are included in at least one embodiment of the present disclosure. Therefore, expression of “in one embodiment” or “in an embodiment” appearing throughout this specification may not necessarily refer to a same embodiment. Furthermore, these specific features, structures, or characteristics may be arbitrarily combined in any suitable manner in one or more embodiments.

As shown inFIG.1toFIG.10, a projection assembly includes: a housing10, a bottom cover20, a display module30, a heat dissipation assembly40and an imaging lens50.

The housing10is connected with the bottom cover20, and the housing10and the bottom cover20form an accommodating space, the heat dissipation assembly40, the display module30and the imaging lens50are all disposed in the accommodating space, and the display module30is disposed on the heat dissipation assembly40. The imaging lens50includes a lens barrel51and a lens assembly52, the lens barrel51is disposed on the heat dissipation assembly40, the lens assembly52is disposed in the lens barrel51, and the lens barrel51surrounds the display module30, the display module30faces the lens assembly52, the housing10is provided with an opening, and the lens assembly52faces the opening.

In the embodiment of the present disclosure, as the housing10is connected with the bottom cover20and the housing10and the bottom cover20form the accommodating space, the heat dissipation assembly40, the display module30and the imaging lens50may be disposed in the accommodating space. Because the display module30is disposed on the heat dissipation assembly40, and the imaging lens50includes the lens barrel51and the lens assembly52, the lens barrel51is disposed on the heat dissipation assembly40, a lens is disposed in the lens barrel51, the lens barrel51surrounds the display module30, and the display module30faces the lens assembly52, light emitted by the display module30can pass through the lens assembly52for imaging through the lens assembly52and heat dissipated by the display module30can be dissipated through the heat dissipation assembly40when the display module30displays an image. As the housing10is provided with the opening and the lens assembly52faces the opening, when the lens assembly52is imaging, the light emitted by the display module30can pass through the lens assembly52and then penetrates out from the opening of the housing10, so that the lens assembly52can image outside the housing10; and when the projection assembly is applied to a vehicle, the light emitted by the display module30passes through the lens assembly52and then can display on a to-be-displayed device in the vehicle, so that a driver can see the image displayed by the display module30on the to-be-displayed device. That is, in the embodiment of the present disclosure, by arranging the heat dissipation assembly40, the display module30and the imaging lens50in the accommodating space formed by the housing10and the bottom cover20, when the display module30displays an image, the image can be displayed through the imaging lens50, and then transmitted to outside of the housing10through the opening in the housing10; moreover, heat dissipation can be made by the heat dissipation assembly40on the projection module30, so that heat generated by the projection assembly can be dissipated by the heat dissipation assembly40during an imaging and projection process of the projection assembly, with a better projection effect of the projection assembly.

It should be noted that in the embodiment of the present disclosure, the lens assembly52may include at least one lens, for example, the lens assembly52includes two lenses. In a case that the lens assembly52includes a plurality of lenses, the plurality of lenses may be convex lenses or concave lenses, a specific arrangement of which may be set according to actual needs, which is not limited here in the embodiment of the present disclosure.

In addition, in the embodiment of the present disclosure, the lens barrel51may include a plurality of sub-barrels which are sleeved with each other. For example, the lens barrel51includes two sub-barrels which are sleeved with each other, that is, one sub-barrel is sleeved on the other sub-barrel and the two sub-barrels are bonded by adhesive001. In a case that the lens barrel51includes two sub-barrels which are sleeved with each other, an inner sub-barrel of the lens barrel51can be made of plastic, and an outer sub-barrel of the lens barrel51can be made of metal or plastic. In a case that the inner sub-barrel of the lens barrel51is made of plastic, the sub-barrel may surround the display module30and function to protect the display module30; and additionally, it is also convenient to process the outer sub-barrel of the lens barrel51. Certainly, the lens barrel51may also include other numbers of sub-barrels. For example, the lens barrel51includes three sub-barrels, which are sleeved with each other. A number of sub-barrels included in the lens barrel51is not limited here in the embodiment of the present disclosure.

In addition, in the embodiment of the present disclosure, a diameter of the lens barrel51may be made large, that is, the lens barrel51may have a larger space at the display module30, so as to prevent the light emitted by the display module30from irradiating an inner wall of the lens barrel51with the lens barrel51surrounding the display module30, thereby affecting imaging effect of the display module30through the lens assembly52.

Moreover, in some embodiments, as shown inFIG.3andFIG.10, the bottom cover20may be provided with a plurality of first air holes21, and the heat dissipation assembly40may include a heat conducting block41and a plurality of heat dissipation fins42. The heat conducting block41includes a first face and a second face which are opposite to each other, the second face faces the plurality of first air holes21on the bottom cover20, the display module30is disposed on the first face, and the plurality of heat dissipation fins42are disposed on the second face.

As the heat dissipation assembly40includes the heat conducting block41and the plurality of heat dissipation fins42, the display module30is disposed on the first face of the heat conducting block41and the plurality of heat dissipation fins42are disposed on the second face of the heat conducting block41, the heat conducting block41can conduct the heat dissipated by the display module30to the plurality of heat dissipation fins42when the display module30dissipates heat. Since the bottom cover20is provided with the plurality of first air holes21and the second face faces the plurality of first air holes21on the bottom cover20, that is, the plurality of heat dissipation fins42face the plurality of first air holes21, the plurality of heat dissipation fins42can conduct the heat outside of the housing10through the plurality of first air holes21when the heat conducting block41conducts heat to the plurality of heat dissipation fins42, so that the heat generated by the display module30can be transferred to outside of the housing10.

It should be noted that, in the embodiment of the present disclosure, a material of the heat conducting block41may be a material that easily conducts heat, for example, the material of the heat conducting block41may be aluminum, and the material of the heat conducting block41may also be copper. The material of the heat conducting block41is not limited here in the embodiment of the present disclosure.

In addition, in the embodiment of the present disclosure, shapes of the heat dissipation fins42may be set according to actual needs, for example, the heat dissipation fins42may be rectangular or wavy in shape. Specific shapes of the heat dissipation fins42are not limited here in the embodiment of the present disclosure. In addition, in the embodiment of the present disclosure, materials of the heat dissipation fins42may be materials that are easy to dissipate heat, for example, the materials of the heat dissipation fin42may be copper, and may also be silver. The materials of the heat dissipation fins42are not limited in the embodiment of the present disclosure.

Moreover, in some embodiments, as shown inFIG.3, the heat dissipation assembly40may also include a heat dissipation fan43, the housing10is provided with a plurality of second air holes11, and the plurality of second air holes11all face the fins. The heat dissipation fan43is disposed at the second face, and the plurality of heat dissipation fins42surround the heat dissipation fan43, and the heat dissipation fan43faces the bottom cover20, so that an air flow generated by the heat dissipation fan43circulates through the first air holes21or the second air holes11.

When the heat dissipation assembly40includes the heat dissipation fan43and the heat dissipation fan43is disposed at the second face, and the plurality of heat dissipation fins42surround the heat dissipation fan43, the heat dissipation fan43can rotate to generate an air flow when the heat conducting block41conducts the heat dissipated by the display module30to the plurality of heat dissipation fins42. Since the housing10is provided with the plurality of second air holes11, the plurality of second air holes11face the heat dissipation fins42, and the heat dissipation fan43faces the bottom cover20, that is, the heat dissipation fan43faces the plurality of first air holes21, air outside the housing10can enter the housing10through the first air holes21or the second air holes11, that is enter the accommodating space, when the heat dissipation fan rotates, so that the heat dissipation fan43can generate an air flow. The air flow circulates through the second air holes11or the first air holes21, that is, flows outside of the housing10through the second air holes11or the first air holes21, thereby transferring the heat generated by the display module30outside of the housing10. That is, by arranging the heat dissipation fan43, an air flow for heat dissipation can be generated in the accommodating space to improve heat dissipation efficiency of the display module30.

It should be noted that, in the embodiment of the present disclosure, the heat dissipation fan43may be an axial fan, or certainly, may also be a radial fan. In a case that the heat dissipation fan43is the axial fan, the first air holes21on the housing10are equivalent to air inlet holes, and the second air holes11on the bottom cover20are equivalent to heat dissipation holes. During rotating of the heat dissipation fan43, the air flow enters the accommodating space from the first air holes21, and then is discharged from the second air holes11, thus forming the air flow for heat dissipation to take the heat dissipated by the display module30out of the housing10. In a case that the heat dissipation fan43is the radial fan, the first air holes11on the housing10are equivalent to heat dissipation holes, and the second air holes11on the bottom cover20are equivalent to air inlet holes. During the rotating of the heat dissipation fan43, the air flow enters the accommodating space from the second air holes21, and then is discharged from the first air holes11, thus forming the air flow for heat dissipation to take the heat dissipated by the display module30out of the housing10. A specific type of the heat dissipation fan43is not limited here in the embodiment of the present disclosure.

Moreover, in some embodiments, as shown inFIG.3, the projection assembly may also include a control circuit60. The control circuit60is disposed in the accommodating space, and the display module30is electrically connected with the control circuit60, and the control circuit60is configured for controlling the display module30to display.

In a case that the projection assembly includes the control circuit60and the display module30is electrically connected with the control circuit60, the control circuit60may send a control signal to the display module30, so that the display module30can display based on the control signal. That is, with the control circuit60being provided, it is convenient to control the display of the display module30.

It should be noted that the control circuit60may be integrated on a Printed Circuit Board (PCB), or certainly, may also be integrated on a Flexible Printed Circuit board (FPC), which is not limited here in the embodiment of the present disclosure.

In addition, in a case that the projection assembly includes the heat dissipation fan43, the heat dissipation fan43may be electrically connected with the control circuit60, so that the control circuit60can also control the heat dissipation fan43. Moreover, in the embodiment of the present disclosure, when the control circuit60is integrated on the printed circuit board, a battery may also be provided on the printed circuit board, and the battery is connected with the heat dissipation fan43to supply power to the heat dissipation fan43.

Moreover, in some embodiments, as shown inFIG.3, the projection assembly may also include a fixing piece70. The fixing piece70is disposed in the accommodating space, the control circuit60is connected with the fixing piece70, and the fixing piece is configured for fixing the control circuit60.

In a case that the projection assembly includes the fixing piece70and the control circuit60is connected with the fixing piece70, the fixing piece70can fix the control circuit60in the accommodating space, that is, the fixing piece70fixes a position of the control circuit60in the accommodating space, thus avoiding a problem that the control circuit60shakes in the accommodating space.

When the control circuit60is integrated on the printed circuit board, the printed circuit board is connected with the fixing piece70, and the fixing piece70fixes the printed circuit board in the accommodating space.

It should be noted that the fixing piece70may be fixedly connected with an inner wall of the housing10, so that a position of the fixing member70in the accommodating space, and thus the position of the control circuit60in the accommodating space, is fixed. In addition, a material of the fixing member70may be plastic or metal, which is not limited here in the embodiment of the present disclosure.

Moreover, in some embodiments, as shown inFIG.3, the projection assembly may also include an interface assembly80. The housing10is provided with a through hole, the interface assembly80is partially located in the accommodating space, and the interface assembly is partially located in the through hole, and the interface assembly80is electrically connected with the control circuit60.

That is, with the interface assembly80be provided, it is possible to facilitate the use of the projection assembly.

It should be noted that the interface assembly80may be a Type-C interface, or certainly, may also be other types of interfaces, which is not limited here in the embodiment of the present disclosure. In addition, in the embodiment of the present disclosure, the interface assembly80may be electrically connected with the control circuit60through a connecting wire.

Moreover, in some embodiments, as shown inFIG.1andFIG.4, the projection assembly may also include a rotary regulating assembly90. The rotary regulating assembly90includes a mounting shell91and a movable connecting piece92. The mounting shell91is provided with an accommodating cavity, a first end of the movable connecting piece92is disposed in the accommodating cavity and is movable in the accommodating cavity, a second end of the movable connecting piece92is connected with the housing10, and the movable connecting piece92is configured for adjusting an angle of the housing10relative to the rotary regulating assembly90. The first end is opposite to the second end.

Since the first end of the movable connecting piece92is disposed in the accommodating cavity of the mounting shell91and can move in the accommodating cavity, the second end of the movable connecting piece92is connected with the housing10, when it is necessary to adjust the angle of the housing10relative to the rotary regulating assembly90, an external force may be applied to the housing10, so that the housing10drives the second end of the movable connecting piece92to move, and thus the first end of the movable connecting piece92can rotate in the accommodating cavity, thereby changing the angle of the housing10relative to the rotary regulating assembly90, and thus changing an angle of the display module30relative to the rotary regulating assembly90in the housing10.

It should be noted that, in the embodiment of the present disclosure, the first end of the movable connecting piece92may be of a spherical shape, and the second end of the movable connecting piece92may be rod-shaped. In this case, the first end of the spherical shape can rotate in the accommodating cavity of the mounting shell91. That is, when it is necessary to adjust the angle of the housing10relative to the rotary regulating assembly90, the housing may be rotated to drive the second end of the movable connecting piece92to move, thereby enabling the first end of the spherical shape to rotate in the accommodating cavity, and the angle of the housing10relative to the rotary regulating assembly90to change. In addition, with the first end of the movable connecting piece92being of the spherical shape, when the first end of the spherical shape rotates in the accommodating cavity, the movable connecting piece92may have three degrees of freedom, and thus the housing10has three degrees of freedom relative to the rotary regulating assembly90.

In addition, in the embodiment of the present disclosure, when the projection assembly is applied to the vehicle and in order to avoid a problem that a joint between the second end of the movable connecting piece92and the housing10is loosened due to vibration of the vehicle when the vehicle is running, adhesive001may be provided at the joint between the second end of the movable connecting piece92and the housing10, so that a gap at the joint between the second end of the movable connecting piece92and the housing10can be blocked.

Moreover, in the embodiment of the present disclosure, the housing10may be provided with a threaded hole and the second end of the movable connecting piece92may be provided with threads, so that the movable connecting piece92can be inserted into the threaded hole, enabling connection between the movable connecting piece92and the housing10.

Moreover, in some embodiments, as shown inFIG.4, the mounting shell91may also be provided with a fastening adjusting piece93. In the case that the angle of the housing10relative to the rotary regulating assembly90is enabled, the fastening adjusting piece93abuts against the first end of the movable connecting piece92to fix the position of the first end of the movable connecting piece92in the accommodating cavity.

In a case that the fastening adjusting piece is disposed on the mounting shell91, when the angle of the housing10relative to the rotary regulating assembly90needs to be adjusted, the housing10is caused to drive the movable connecting piece92to move, that is, to make the first end of the movable connecting piece92rotate in the accommodating cavity, and when the angle of the housing10relative to the rotary regulating assembly90is enabled, the first end of the movable connecting piece92can be caused not to rotate in the accommodating cavity by abutting the fastening adjusting piece93against the first end of the movable connecting piece92, so that the position of the movable connecting piece92in the accommodating cavity, and thus the angle of the housing10relative to the rotary regulating assembly90, is fixed. That is, with the fastening adjusting piece93being provided, the position of the housing10can be fixed when the angle of the housing10relative to the rotation adjustment assembly90is enabled.

It should be noted that, in the embodiment of the present disclosure, the fastening adjusting piece93may be a fastening screw, and when the housing10is rotated to enable the angle between the housing10and the rotary regulating assembly90, the fastening screw may be rotated, such that the fastening screw abuts against the first end of the movable connecting piece92to cause the first end of the movable connecting piece92and the accommodating cavity of the mounting shell91not to rotate relatively; and the position of the movable connecting piece92, and thus the position of the housing10, is fixed. In other words, the angle between the housing10and the rotary regulating assembly90does not change any longer. When it is necessary to readjust the angle between the housing10and the rotary regulating assembly90, the fastening screw may be rotated again to make the fastening screw no longer abut against the first end of the movable connecting piece92to enable the first end of the movable connecting piece92to rotate relative to the accommodating cavity of the mounting shell91, thereby adjusting the angle of the housing10relative to the rotary regulating assembly90. It should be noted that adjusting the angle of the housing10relative to the rotary regulating assembly90is essentially to adjust an angle of the display module30relative to the rotary regulating assembly90.

Moreover, in some embodiments, as shown inFIG.4andFIG.5, the projection assembly may further include a mounting bracket100, the mounting shell91may include a movable part911and a connecting part912, and the movable part911is connected with the connecting part912. The accommodating cavity is disposed in the movable part911, the mounting bracket100is detachably connected with the connecting part912, and the mounting bracket100is configured for mounting the mounting shell91to the vehicle.

Since the mounting bracket100is detachably connected with the connecting part912of the mounting shell91, when the mounting shell91needs to be replaced, the mounting shell91may be detached from the mounting bracket to replace the mounting shell91, and then the replaced mounting shell91may be connected to the mounting bracket100. In addition, the mounting bracket100may be fixed in the vehicle, so that the projection assembly can be mounted in the vehicle by mounting the mounting shell91to the vehicle with the mounting bracket100.

It should be noted that, in the embodiment of the present disclosure, the mounting bracket100may be connected with the connecting part912of the mounting shell91by a bolt, that is, the movable part911is provided with a threaded hole, the mounting bracket100is provided with a through hole, and the mounting bracket100is connected with the mounting shell91by passing the bolt through the through hole and inserting the bolt into the threaded hole on the movable part911.

In addition, when the mounting shell91is mounted to the vehicle with the mounting bracket100and in order to avoid a problem that the joint between the mounting bracket100and the mounting shell91is loosened due to the vibration of the vehicle during traveling of the vehicle, the adhesive001may be provided at the joint between the mounting bracket100and the housing10of the mounting shell91, and the gap between the mounting bracket100and the housing10of the mounting shell91can be blocked by the adhesive001, thus avoiding the problem that the joint between the mounting bracket100and the mounting shell91is loosened due to the vibration of the vehicle. In addition, in a case that the mounting bracket100and the mounting shell91are connected by the bolt, the adhesive001is provided at the gap between the mounting bracket100and the mounting shell91. The adhesive001can not only block the gap between the mounting bracket100and the mounting shell91, but also be bonded to the bolt, such that the mounting bracket100and the mounting shell91are connected more firmly.

Moreover, in some embodiments, as shown inFIG.1, the projection assembly may also include a restrained support110. The restrained support110has a plate structure, and the restrained support110includes a first surface and a second surface which are opposite to each other; an end of the mounting bracket100is connected with the first surface, the second surface is provided with a bonding piece configured for bonding the restrained support110in the vehicle.

In a case that the projection assembly includes the restrained support110, the end of the mounting bracket100is connected with the first surface of the restrained support110, and the second surface of the mounting bracket100is provided with the bonding piece, when it is necessary to connect the restrained support110to the vehicle so as to mount the projection assembly in the vehicle, the second surface of the restrained support110can be directly bonded to a position in the vehicle where mounting is to be made, so that the projection assembly can be installed in the vehicle, with easy mounting of the projection assembly in the vehicle.

It should be noted that the restrained support110may be provided with a cutout1101, so that the restrained support110can adapt to mounting positions for different vehicles. When the projection assembly is mounted in the vehicle, the projection assembly is usually mounted at a center console of the vehicle. That is, with the cutout1101being provided on the restrained support110, the restrained support110can adapt to center consoles of different vehicles, with versatility of the projection assembly. In addition, both a shape and a number of the cutout1101may be set according to actual needs, which are not limited here in the embodiment of the present disclosure.

Moreover, in the embodiment of the present disclosure, the mounting bracket100may be connected with the restrained support100by bolts, or certainly, may also be connected in other ways, such as snap connection, which is not limited here in the embodiment of the present disclosure.

Because the display module30is disposed on the heat dissipation assembly40, and the imaging lens50includes the lens barrel51and the lens assembly52, with lens barrel51being disposed on the heat dissipation assembly40, the lens being disposed in the lens barrel51, the lens barrel51surrounding the display module30, and the display module30facing the lens assembly52, light emitted by the display module30can pass through and image through the lens assembly52and heat dissipated by the display module can be dissipated through the heat dissipation assembly40, when the display module30displays an image. As the housing10is provided with the opening and the lens assembly52faces the opening, when the lens assembly52is imaging, the light emitted by the display module can pass through the lens assembly52and then penetrates out from the opening of the housing10, so that the lens assembly52can image outside the housing10; and when the projection assembly is applied to a vehicle, the light emitted by the display module30passes through the lens assembly52and then can display on a to-be-displayed device in the vehicle, so that a driver can see the image displayed by the display module30on the to-be-displayed device.
