Description

Technical Field

[0001] This invention relates to the field of projection technology, and more particularly to a high-brightness projector. Background Technology

[0002] Existing high-brightness projectors typically have ventilation openings on their casing and use fans to drive airflow inside the casing. However, some high-brightness projectors have unreasonable layouts in terms of air intake and exhaust positions, as well as the arrangement of the fan and the projection engine. The air intake and exhaust are too close together, which can easily cause airflow short-circuiting. This results in the air entering the casing not flowing sufficiently through the projection engine before being directly exhausted, making it difficult to dissipate heat near the projection engine in a timely manner. Summary of the Invention

[0003] In view of this, the present invention provides a high-brightness projector to solve the technical problem of poor heat dissipation in high-brightness projectors in related technologies.

[0004] This invention provides the following technical solution: A high-brightness projector includes: a lower housing, a driver, and a projection optical engine; The lower housing includes a bottom wall and a peripheral wall. The bottom wall is provided with a first ventilation section, and the peripheral wall is provided with a second ventilation section. The first ventilation section is disposed away from the second ventilation section. The driving component is disposed on the side of the bottom wall away from the first ventilation section. The projection optical engine is disposed on the bottom wall and between the first ventilation section and the second ventilation section. The drive component is disposed on the bottom wall, and the drive component is used to drive airflow from the first ventilation section into the lower housing and out from the second ventilation section.

[0005] Furthermore, the peripheral wall includes a front wall and a rear wall disposed opposite to each other, and a first side wall and a second side wall respectively connected between the front wall and the rear wall; The second ventilation section is disposed in at least one of the front wall, the rear wall, the first side wall, and the second side wall.

[0006] Furthermore, the second ventilation section is disposed on the front wall and the rear wall, and the driving member includes: an air inlet, a first air outlet and a second air outlet, wherein the first air outlet faces the front wall, the second air outlet faces the rear wall, and the air inlet faces the first ventilation section.

[0007] Furthermore, the high-brightness projector also includes a heat dissipation structure, which includes a heat-absorbing element, a heat pipe assembly, and a heat sink. The heat-absorbing element is attached to the projection optical engine, one end of the heat pipe assembly is thermally connected to the heat-absorbing element, and the other end of the heat pipe assembly passes through the heat sink. The heat sink is located at the second air outlet.

[0008] Furthermore, it also includes: a drive mechanism; The projection optical engine also includes a projection lens, and the driving mechanism is disposed on one side of the projection lens. The driving mechanism is used to drive the projection lens to rotate.

[0009] Furthermore, the drive mechanism includes: a drive motor and a drive gear; The drive motor is mounted on the projection optical engine, the drive gear is mounted on the drive motor, and the outer periphery of the projection lens is provided with a meshing part. The drive gear cooperates with the meshing part to drive the projection lens to rotate.

[0010] Furthermore, the high-brightness projector also includes a support assembly disposed below the lower shell, the support assembly being rotatably connected to the lower shell, and an air intake gap communicating with the first ventilation section is formed between the support assembly and the lower shell.

[0011] Furthermore, it also includes: an angle adjustment component; The angle adjustment component is disposed between the support component and the housing so that the high-brightness projector can rotate about the rotation axis relative to the support component.

[0012] Furthermore, the angle adjustment assembly includes a first connecting plate, a second connecting plate, a rotating shaft, a fastener, and an elastic element; The pivot is inserted through the support assembly and the housing. The first connecting plate and the second connecting plate are both disposed on the pivot. The first connecting plate is connected to the support assembly, and the second connecting plate is connected to the housing. The elastic element is sleeved on the pivot. One side of the elastic element abuts against the second connecting plate, and the other side abuts against the fastener.

[0013] Furthermore, the angle adjustment assembly also includes a friction element and a pressure-bearing element, wherein the friction element is sleeved on the rotating shaft and disposed between the support assembly and the housing. The pressure-bearing component is annular and sleeved on the rotating shaft component, and the pressure-bearing component is disposed between the elastic component and the fastener.

[0014] This invention provides a high-brightness projector, including a lower housing, a drive unit, and a projection optical engine.

Thus, when the high-brightness projector is operating, the drive unit activates and drives external airflow into the lower housing through the first ventilation section. Since the projection optical engine is located between the first and second ventilation sections, the airflow entering the lower housing can flow along this airflow path through the area where the projection optical engine is located, absorbing the heat generated during the operation of the projection optical engine. Subsequently, under the action of the drive unit, the airflow is discharged through the second ventilation section, allowing the airflow to fully pass through the area where the projection optical engine is located and carry away heat, thereby improving the heat dissipation efficiency of the high-brightness projector, reducing heat accumulation in the lower housing, and improving the operational stability of the projection optical engine during long-term operation.

[0021] Please see Figure 1 and Figure 2 A high-brightness projector 100 includes: a lower housing 10, a driver 20, and a projection optical engine 30; The lower housing 10 includes a bottom wall 11 and a peripheral wall 12. The bottom wall 11 is provided with a first ventilation section 111, and the peripheral wall 12 is provided with a second ventilation section 121. The first ventilation section 111 is disposed away from the second ventilation section 121. The driving member 20 is disposed on the side of the bottom wall 11 away from the first ventilation section 111. The projection optical engine 30 is disposed on the bottom wall 11 and between the first ventilation section 111 and the second ventilation section 121. The driving component 20 is disposed on the bottom wall 11, and the driving component 20 is used to drive airflow from the first ventilation section 111 into the lower housing 10 and out from the second ventilation section 121.

[0022] This invention provides a high-brightness projector 100, including a lower housing 10, a drive unit 20, and a projection optical engine 30. The bottom wall 11 and the peripheral wall 12 together form an internal space for accommodating the projection optical engine 30 and the drive unit 20. A first ventilation section 111 is provided on the bottom wall 11, and a second ventilation section 121 is provided on the side wall. The first ventilation section 111 is used for airflow entering the lower housing 10, and the second ventilation section 121 is used for airflow exiting the lower housing 10. The first ventilation section 111 and the second ventilation section 121 are spaced apart, forming an airflow path of a certain length between them. Thus, when the high-brightness projector 100 is operating, the drive unit 20 is activated and drives external airflow through the first ventilation section 111 into the lower housing 10. Since the projection optical engine 30 is located between the first ventilation section 111 and the second ventilation section 121, the airflow entering the lower housing 10 can flow along the airflow path through the area where the projection optical engine 30 is located, absorb the heat generated when the projection optical engine 30 is working, and then be discharged from the second ventilation section 121 under the action of the drive member 20, so that the airflow can flow through the area where the projection optical engine 30 is located more fully and carry away the heat, thereby improving the heat dissipation efficiency of the high-brightness projector 100, reducing the accumulation of heat in the lower housing 10, and improving the operational stability of the projection optical engine 30 during long-term operation.

[0023] Please see Figure 1 and Figure 2 In some embodiments, the peripheral wall 12 includes a front wall 13 and a rear wall 14 disposed opposite to each other, and a first side wall 15 and a second side wall 16 respectively connected between the front wall 13 and the rear wall 14. The second ventilation section 121 is disposed in at least one of the front wall 13, the rear wall 14, the first side wall 15, and the second side wall 16.

[0024] It is understood that the front wall 13 and the rear wall 14 are arranged opposite each other, and the first side wall 15 and the second side wall 16 are respectively located between the front wall 13 and the rear wall 14, so that the four walls together form the circumferential structure of the lower shell 10. The second ventilation section 121 can be arranged on one of the four walls, or it can be arranged on multiple walls at the same time. When the second ventilation section 121 is arranged on one wall, the airflow in the lower shell 10 is mainly discharged outward from that wall; when the second ventilation section 121 is arranged on multiple walls, the airflow can flow to the corresponding wall and be discharged by the corresponding second ventilation section 121. Specifically, it can be arranged according to the relative position of the heat-generating component and the driving component 20 inside the high-brightness projector 100, so that the position of the second ventilation section 121 is adapted to the airflow direction in the lower shell 10, so as to improve the heat dissipation efficiency.

[0025] In some embodiments, a plurality of cover plates 80 are provided on the lower housing 10 so that the high-brightness projector 100 forms a sealed structure.

[0026] In some embodiments, the second ventilation section 121 is disposed on the front wall 13 and the rear wall 14, and the drive member 20 includes an air inlet, a first air outlet and a second air outlet, wherein the first air outlet faces the front wall 13, the second air outlet faces the rear wall 14, and the air inlet faces the first ventilation section 111.

[0027] Understandably, the air inlet faces the first ventilation section 111, allowing the airflow entering the lower housing 10 through the first ventilation section 111 to converge at the air inlet of the drive unit 20. When the drive unit 20 is operating, the air inlet continuously guides external airflow from the first ventilation section 111 into the lower housing 10, and also allows airflow passing through the area where the projection optical engine 30 is located to enter the drive unit 20. The airflow entering the drive unit 20 is then discharged through the first air outlet and the second air outlet. Since the first air outlet faces the front wall 13, the airflow discharged from the first air outlet can flow to the second ventilation section 121 on the front wall 13; the second air outlet faces the rear wall 14, and the airflow discharged from the second air outlet can flow to the second ventilation section 121 on the rear wall 14. This creates two exhaust paths in the front and rear directions. These two exhaust paths reduce turbulence inside the lower housing 10, allowing the airflow discharged from the drive unit 20 to exit the lower housing 10 more smoothly, thereby improving heat dissipation.

[0028] Please see Figure 3In some embodiments, the high-brightness projector 100 further includes a heat dissipation structure 40, which includes a heat-absorbing element 41, a heat pipe assembly 42, and a heat sink 43. The heat-absorbing element 41 is attached to the projection optical engine 30, one end of the heat pipe assembly 42 is thermally connected to the heat-absorbing element 41, and the other end of the heat pipe assembly 42 passes through the heat sink 43. The heat sink 43 is disposed at the second air outlet.

[0029] Understandably, the heat absorber 41 is attached to the projection optical engine 30. The heat generated by the projection optical engine 30 during operation can be transferred from the projection optical engine 30 to the heat absorber 41. The heat absorber 41 receives and collects the heat generated by the projection optical engine 30. One end of the heat pipe assembly 42 is thermally connected to the heat absorber 41, allowing the heat received by the heat absorber 41 to be transferred to the heat pipe assembly 42. The other end of the heat pipe assembly 42 passes through the heat sink 43, allowing the heat in the heat pipe assembly 42 to be further transferred to the heat sink 43. This allows the heat near the projection optical engine 30 to be transferred to the location of the heat sink 43. The heat sink 43 is located in the second air outlet, placing it in the area through which the airflow from the drive unit 20 passes. The airflow from the second air outlet continuously flows through the heat sink 43 and carries away the heat from it. When the drive unit 20 is working, the airflow delivered by the second air outlet exchanges heat with the radiator 43. After absorbing heat, the airflow continues to flow to the second ventilation section 121 on the rear wall 14 and is discharged from the lower housing 10 through the second ventilation section 121. When it is discharged from the lower housing 10, it can also cool the radiator 43, thereby further improving the heat dissipation effect and reducing the accumulation of heat around the projection optical engine 30.

[0030] Please see Figure 1 and Figure 4 In some embodiments, it further includes: a drive mechanism 50; The projection optical engine 30 also includes a projection lens 31, and the driving mechanism 50 is disposed on one side of the projection lens 31. The driving mechanism 50 is used to drive the projection lens 31 to rotate.

[0031] Understandably, the drive mechanism 50 is positioned on one side of the projection lens 31, enabling it to transmit driving force to the projection lens 31 from a position close to it. Specifically, when the projection lens 31 needs adjustment, the drive mechanism 50 outputs driving force, causing the projection lens 31 to rotate under this force. This changes the rotation state and position of the projection lens 31, thereby achieving rotational control and optical adjustment of the projection lens 31.

[0032] Please see Figure 1 and Figure 4 In some embodiments, the drive mechanism 50 includes a drive motor 51 and a drive gear 52; The drive motor 51 is mounted on the projection optical engine 30, the drive gear 52 is mounted on the drive motor 51, and the outer periphery of the projection lens 31 is provided with a meshing part 32. The drive gear 52 cooperates with the meshing part 32 to drive the projection lens 31 to rotate.

[0033] Understandably, the drive motor 51 is mounted on the projection optical engine 30, and the drive gear 52 is mounted on the drive motor 51, allowing the drive gear 52 to be driven by the drive motor 51. To enable the drive gear 52 to drive the projection lens 31, a meshing portion 32 is provided on the outer periphery of the projection lens 31. The meshing portion 32 matches the size of the drive gear 52 and meshes with it. When the drive gear 52 rotates, it transmits rotation and torque to the projection lens 31 through the meshing action with the meshing portion 32, causing the projection lens 31 to rotate with the drive gear 52, thereby achieving lens adjustment. Through the cooperation of the drive motor 51, the drive gear 52, and the meshing portion 32, the rotation of the projection lens 31 can be driven more directly, making the rotation process of the projection lens 31 smoother and more reliable, and facilitating control of the rotation amount.

[0034] Please see Figure 5 In some embodiments, the high-brightness projector 100 further includes a support component 60 disposed below the lower shell, the support component 60 being rotatably connected to the lower shell, and an air inlet gap being formed between the support component 60 and the lower shell, communicating with the first ventilation section 111.

[0035] Understandably, the support assembly 60 is located below the lower shell to support the high-brightness projector 100. When the high-brightness projector 100 is placed on the support surface, the support assembly 60 is positioned between the lower shell and the support surface, preventing the lower shell from directly contacting the support surface and reserving space for air intake in the first ventilation section 111 at the bottom of the lower shell. By setting the support assembly 60 and the air intake gap, the possibility of the first ventilation section 111 being blocked due to the high-brightness projector 100 being placed on the support surface can be reduced, allowing the first ventilation section 111 to maintain continuous communication with the external environment and providing a smoother air intake source for the drive unit 20. When the drive unit 20 is operating, external airflow can enter the air intake gap around the support assembly 60 and then enter the interior of the lower shell through the first ventilation section 111. The rotatable connection between the support assembly 60 and the lower shell also provides a basis for adjusting the position of the high-brightness projector 100 while ensuring air intake. The rotatable connection between the support assembly 60 and the lower shell allows the lower shell to rotate relative to the support assembly 60. This allows the high-brightness projector 100 to adjust its position relative to the support assembly 60.

[0036] Please see Figure 5In some embodiments, it also includes: an angle adjustment component 70; The angle adjustment component 70 is disposed between the support component 60 and the housing so that the high-brightness projector 100 can rotate about the rotation axis relative to the support component 60.

[0037] Understandably, the angle adjustment component 70 is located at the connection point between the support component 60 and the housing, acting on the support component 60 on one side and the housing on the other. The angle adjustment component 70 establishes a rotatable connection between the support component 60 and the housing, allowing this relative rotation to occur around a rotation axis. When adjusting the angle of the high-brightness projector 100, the housing rotates relative to the support component 60 around the rotation axis under the action of an external force, and the projection posture of the high-brightness projector 100 changes along with the housing. In this way, the angle of the high-brightness projector 100 can be adjusted through the relative rotation between the housing and the support component 60, facilitating the adjustment of the projection angle according to the placement position and projection target of the high-brightness projector 100, and improving the adaptability of the high-brightness projector 100 to different usage positions.

[0038] Please see Figure 6 In some embodiments, the angle adjustment assembly 70 includes a first connecting plate 71, a second connecting plate 72, a rotating shaft 73, a fastener 74, and an elastic element 75. The pivot 73 passes through the support assembly 60 and the housing. The first connecting plate 71 and the second connecting plate 72 are both disposed on the pivot 73. The first connecting plate 71 is connected to the support assembly 60, and the second connecting plate 72 is connected to the housing. The elastic member 75 is sleeved on the pivot 73. One side of the elastic member 75 abuts against the second connecting plate 72, and the other side abuts against the fastener 74.

[0039] Understandably, the angle adjustment assembly 70 includes a first connecting plate 71, a second connecting plate 72, a pivot 73, a fastener 74, and an elastic element 75. The pivot 73 passes through the support assembly 60 and the housing. The first connecting plate 71 is connected to the support assembly 60, and the second connecting plate 72 is connected to the housing. Both the first connecting plate 71 and the second connecting plate 72 are mounted on the pivot 73. The first connecting plate 71 and the second connecting plate 72 can be connected to the support assembly 60 and the housing respectively by bolts, welding, riveting, or other mechanical connection methods. The elastic element 75 is sleeved on the pivot 73, with one side abutting against the second connecting plate 72 and the other side abutting against the fastener 74. The pivot 73 can be a cylindrical rod-shaped structure made of stainless steel or alloy steel and can cooperate with bearings or bushings to reduce rotational friction. The fastener 74 restricts the side of the elastic element 75 away from the second connecting plate 72, so that the elastic element 75 applies a continuous axial elastic force to the connection part where the second connecting plate 72 is located. This axial force keeps the connecting parts of the angle adjustment assembly 70 in contact with each other. By adjusting the tightness of the fasteners 74, the compression of the elastic element 75 and the axial force can be changed, thereby adjusting the rotational damping or locking force of the angle adjustment assembly 70. When rotation is required, the support assembly is rotated along the axis of the rotating element to achieve angle adjustment and ensure that the high-brightness projector 100 body remains stable at the target angle.

[0040] Please see Figure 6 In some embodiments, the angle adjustment assembly 70 further includes a friction element 76 and a pressure-bearing element 77. The friction element 76 is sleeved on the rotating shaft 73 and disposed between the support assembly 60 and the housing. The pressure-bearing member 77 is annular and sleeved on the rotating shaft member 73, and the pressure-bearing member 77 is disposed between the elastic member 75 and the fastener 74.

[0041] Understandably, the angle adjustment assembly 70 also includes a friction element 76 and a pressure-bearing element 77. The friction element 76 is sleeved on the rotating shaft 73 and positioned between the support assembly 60 and the housing. The axial force generated by the elastic element 75 presses the friction element 76 between the support assembly 60 and the housing, converting the axial force into frictional force to limit relative rotation. This restricts the rotation of the high-brightness projector 100 body, preventing accidental rotation caused by its own weight, vibration, or minor impacts. The pressure-bearing element 77 is annular and sleeved on the rotating shaft 73, positioned between the elastic element 75 and the fastener 74, to transmit the axial force of the fastener 74 to the elastic element 75. Located between the fastener 74 and the elastic element 75, the pressure-bearing element 77 can distribute and transmit the localized axial force applied by the fastener 74 more evenly to the elastic element 75, reducing the possibility of localized stress concentration, wear, or deformation of the elastic element 75.

[0042] Optionally, both the friction element 76 and the pressure-bearing element 77 can be annular gaskets, and can be made of engineering plastics, composite materials, rubber, or surface-treated metals with a high coefficient of friction. The material and structure of the friction element 76 can be set according to the required frictional resistance to allow the user to apply external force for rotational adjustment while maintaining the target angle.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of the present invention should not depart from the spirit and scope of the technical solutions of the present invention.
