Abstract
Description
Technical Field
[0001] This utility model relates to the field of projector technology, and in particular to a gimbal-mounted projector. Background Technology
[0002] Projectors convert image or video signals into light signals and project them onto a screen through an optical lens. They are widely used in education, business, entertainment and many other fields.
[0003] In the existing technology, projectors need to be mounted on a gimbal bracket. The existing projector gimbal bracket can only adjust the projection angle and cannot protect the projection lens. An additional lens cap is required to protect the projection lens. In addition, in the existing heat dissipation structure of projectors, the air intake uses a single air intake blower, or an exhaust blower (no fan for air intake), or an air intake blower and an axial fan for air exhaust, which results in the heat dissipation effect of the projector being less than ideal.
[0004] Therefore, a gimbal-mounted projector is proposed. Utility Model Content
[0005] In order to improve the problems of existing projector stands failing to protect the projector lens and the projector's heat dissipation being inadequate, this utility model provides a gimbal-mounted projector.
[0006] This utility model provides a gimbal-mounted projector, which adopts the following technical solution:
[0007] A gimbal-mounted projector includes a projector body and a support for supporting the projector body. The inner wall of the support is provided with a pivot, and the projector body is hinged to the support via the pivot. The projector body has a light chamber inside, and a screen is provided at the front end of the light chamber inside the projector body. A projection lens is provided at the front end of the projector body, and an arc-shaped groove for protecting the projection lens is provided at one end of the support.
[0008] An intake fan is provided on one side of the projector body, and an exhaust fan is provided on the side of the projector body away from the intake fan. A heat sink is provided on the back of the projector body. A heat dissipation channel is formed inside the projector body, which connects the intake fan, the exhaust fan and the heat sink in sequence. A front Felix lens and a rear Felix lens are provided on both sides of the screen, and both the front Felix lens and the rear Felix lens are located in the heat dissipation channel.
[0009] By adopting the above technical solution, the projector body can be rotated around the pivot when in use, allowing the projection lens to disengage from the arc-shaped groove of the bracket, thus enabling projection. Since the projector body can rotate freely around the pivot, the projection angle can be freely adjusted. When not in use, the projector body can be rotated to allow the projection lens to re-enter the arc-shaped groove of the bracket, protecting the lens without the need for an additional lens cap, making it more convenient to use. With the inclusion of an intake fan, exhaust fan, heat sink, and heat dissipation channel, both the intake and exhaust fans can be activated simultaneously during projector operation. The intake fan draws in cool air from the outside and delivers it to the heat dissipation channel. As the cool air passes over the front and rear Fresnel lenses, it removes heat from the LED lights projected onto the heat-insulating glass and screen. The hot air is then drawn out by the exhaust fan, passes through the heat dissipation channel, and is blown towards the heat sink for exhaust, achieving efficient heat dissipation and improving overall cooling efficiency.
[0010] Optionally, one end of the bracket is provided with four pads, which are evenly distributed at the four corners of the bracket.
[0011] By adopting the above technical solution, the pads can provide anti-slip support for the stand, allowing the stand to be stably placed on the table when using the projector.
[0012] Optionally, a power board is installed inside the projector body.
[0013] By adopting the above technical solution, the power board is used to control the power supply of the projector.
[0014] Optionally, both the intake fan and the exhaust fan are blowers.
[0015] By adopting the above technical solution, the blower fan has a high pressure coefficient and a relatively low flow coefficient, which can accelerate the airflow.
[0016] Optionally, a speaker is provided on one side of the projector body located in the light chamber.
[0017] By adopting the above technical solution, a speaker is used to emit sound when the projector is in use.
[0018] Optionally, an LED light is provided inside the projector body at one end of the light chamber.
[0019] By adopting the above technical solution, LED lights are used to provide illumination to the light chamber.
[0020] Optionally, a dustproof screen is provided on the side of the projector body near the air intake fan.
[0021] By adopting the above technical solution and setting up a dustproof net, the inlet of the air intake fan can be blocked from dust, which can reduce the entry of dust and other impurities into the air intake fan, thereby reducing the entry of dust into the projector and preventing dust from affecting the air intake fan and the components inside the projector.
[0022] Optionally, heat-insulating glass is provided inside the projector body between the screen and the rear mirror.
[0023] By adopting the above technical solution, the heat-insulating glass can play a heat-insulating role between the screen and the rear mirror, dispersing the airflow generated by the intake fan to both sides of the heat-insulating glass. Part of it flows through the space between the screen and the heat-insulating glass and then enters the exhaust fan, where it is drawn to the radiator and discharged as hot air. The other part flows through the space between the rear mirror and the heat-insulating glass and blows directly onto the radiator to discharge hot air, thus achieving multi-channel heat dissipation and improving heat dissipation efficiency.
[0024] In summary, this utility model has the following beneficial effects:
[0025] 1. This utility model, through the design of the bracket, allows the projector body to rotate around a pivot when in use, causing the projector lens to disengage from the arc-shaped groove of the bracket, thus enabling projection. Since the projector body can rotate freely around the pivot, the projection angle can be freely adjusted. When the projector is not in use, the projector body can be rotated to allow the projector lens to retract into the arc-shaped groove of the bracket, thereby protecting the projector lens without the need for an additional lens cap, making it more convenient to use.
[0026] 2. This utility model, through the arrangement of an intake fan, an exhaust fan, a radiator, and a heat dissipation channel, allows the intake and exhaust fans to be activated simultaneously when the projector is working. The intake fan draws in cool air from the outside and then delivers it to the heat dissipation channel. As the cool air passes through the front and rear lenses, it carries away the heat projected by the LED lights onto the heat-insulating glass and screen. The hot air is then drawn out by the exhaust fan, passes through the heat dissipation channel, and blown towards the radiator to expel the hot air, thus achieving efficient heat dissipation of the projector and improving its heat dissipation efficiency.

[0034] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0035] Please refer to Figure 1-3A gimbal-mounted projector includes a projector body 1 and a support 2 for supporting the projector body 1. Four pads 23 are evenly distributed at the four corners of the support 2 at one end, providing anti-slip support. During use, the support 2 can be stably placed on a table. A hinge 21 is provided on the inner wall of the support 2, through which the projector body 1 is hinged to the support 2. A light chamber 11 is provided inside the projector body 1, and a screen 12 is located at the front end of the light chamber 11. A projection lens 13 is located at the front end of the projector body 1. An arc-shaped groove 22 is provided at one end of the support 2 to protect the projection lens 13. The projection lens 13 and the arc-shaped groove 22 are connected. The two parts fit together perfectly with a very small gap, allowing the projection lens 13 of the projector body 1 to smoothly rotate out of the bracket 2 during use. With the bracket 2 in place, the projector body 1 can be rotated around the pivot 21 during use, causing the projection lens 13 to disengage from the arc-shaped groove 22 of the bracket 2, thus enabling projection through the lens 13. Since the projector body 1 can rotate freely around the pivot 21, the projection angle can be freely adjusted. When the projector is not in use, the projector body 1 can be rotated to allow the projection lens 13 to re-enter the arc-shaped groove 22 of the bracket 2, thus protecting the projection lens 13 without the need for an additional lens cap, making it easier to protect the projector lens and more convenient to use.
[0036] Furthermore, compared to the structure where the projector body must be lifted up to separate from the base before the projector can be rotated out, this application allows the projector body 1 to be rotated out directly from the bracket 2, making it more convenient to use.
[0037] Reference Figure 5 When using the projector, place the stand vertically on the table, and then rotate the projector body 1 90 degrees from bottom to top and towards the front around the pivot 21 of the stand 2 to project. Normally, it rotates 90 degrees, but it can also rotate 180 degrees. When rotated to 180 degrees, the projection lens 13 faces the ceiling.
[0038] Reference Figures 2-4An intake fan 14 is provided on one side of the projector body 1, and an exhaust fan 15 is provided on the side of the projector body 1 away from the intake fan 14. Both the intake fan 14 and the exhaust fan 15 are blowers. A heat sink 16 is provided on the back of the projector body 1. A heat dissipation channel 17 is formed inside the projector body 1, which connects the intake fan 14, the exhaust fan 15, and the heat sink 16 in sequence. A front Faraday mirror 18 and a rear Faraday mirror 19 are provided on both sides of the screen 12, and both the front Faraday mirror 18 and the rear Faraday mirror 19 are located within the heat dissipation channel 17. A power board 110 is provided inside the projector body 1, and a speaker 111 is provided on the side of the projector body 1 located on the light box 11. An LED lamp 112 is installed at one end of the light chamber 11 inside the projector body 1. With the arrangement of an intake fan 14, an exhaust fan 15, a heat sink 16, and a heat dissipation channel 17, the intake fan 14 and the exhaust fan 15 can be activated simultaneously when the projector is working. The intake fan 14 draws in cool air from the outside and then delivers the cool air into the heat dissipation channel 17. When the cool air passes through the front lens 18 and the rear lens 19, it can remove the heat projected by the LED lamp 112 onto the heat-insulating glass 114 and the screen 12. The hot air is then drawn out by the exhaust fan 15, blown towards the heat sink after passing through the heat dissipation channel 17, and discharged from the heat sink, thus achieving efficient heat dissipation of the projector and improving heat dissipation efficiency.
[0039] The projector body 1 is provided with a dustproof net 113 on the side near the air intake fan 14. The dustproof net 113 can block the air intake fan 14 from dust, reducing the entry of dust and other impurities into the air intake fan 14, thereby reducing the entry of dust into the projector and preventing dust from affecting the air intake fan 14 and the components inside the projector.
[0040] The projector body 1 has a heat-insulating glass 114 located between the screen 12 and the rear mirror 19. The heat-insulating glass 114 can provide heat insulation between the screen 12 and the rear mirror 19, and disperse the airflow generated by the intake fan 14 to both sides of the heat-insulating glass 114. Part of the airflow flows between the screen 12 and the heat-insulating glass 114 and then enters the exhaust fan 15. The exhaust fan 15 draws the hot air to the heat sink and discharges it. The other part flows between the rear mirror 19 and the heat-insulating glass 114 and blows the hot air directly to the heat sink to discharge it. This achieves multi-channel heat dissipation and improves heat dissipation efficiency.
[0041] The implementation principle of this utility model is as follows: With the support 2, the pad 23 provides anti-slip support. When using the projector, the support 2 can be stably placed on the table. When using the projector, the projector body 1 can be rotated around the pivot 21, causing the projector lens 13 to disengage from the arc-shaped groove 22 of the support 2, allowing projection through the lens 13. Since the projector body 1 can rotate freely around the pivot 21, the projection angle can be freely adjusted. When not using the projector, the projector body 1 can be rotated to allow the projector lens 13 to enter the arc-shaped groove 22 of the support 2, thus protecting the projector lens 13 without the need for an additional lens cap, making it easier to protect the projector lens and more convenient to use. With the arrangement of the intake fan 14, exhaust fan 15, heat sink 16, and heat dissipation channel 17, the intake fan 14 and exhaust fan 15 can be activated simultaneously when the projector is working. The intake fan 14 draws in cool air from the outside and then delivers the cool air to the heat dissipation channel 17. Inside, as cool air passes through the front and rear Fresnel lenses 18 and 19, it carries away the heat projected by the LED lights 112 onto the heat-insulating glass 114 and screen 12. The hot air is then drawn in by the exhaust fan 15, passes through the heat dissipation channel 17, and is blown towards the heat sink to expel the hot air, achieving efficient heat dissipation for the projector. The dust filter 113 prevents dust from entering the intake fan 14, thus reducing the amount of dust entering the projector and preventing dust from contaminating the intake fan 14 and the projector's internal components. The heat insulation glass 114 can be used to insulate the screen 12 and the rear mirror 19, thus dispersing the airflow generated by the intake fan 14 to both sides of the heat insulation glass 114. Part of the airflow flows between the screen 12 and the heat insulation glass 114 and then enters the exhaust fan 15, where it is drawn to the heat sink and discharged as hot air. The other part flows between the rear mirror 19 and the heat insulation glass 114 and blows directly onto the heat sink to discharge hot air, thus achieving multi-channel heat dissipation and improving heat dissipation efficiency.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
