Description

Technical Field

[0001] The utility model relates to the field of projector products, in particular to a projector with stable placement. Background Art

[0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It is widely used in homes, offices, schools and entertainment venues.

[0003] Traditionally, a projector is generally placed on a carrier, and the carrier is placed on the ground. Specifically, the height of the carrier and the distance between the projection surface are adjusted according to the corresponding environment, thereby adjusting the clarity of the projector projection. When an existing projector is placed on the top surface of the carrier, it cannot be directly fixed on the top surface of the carrier, resulting in poor stability between the projector and the carrier. In fact, even if the projector is fixed to the carrier by bolts or other workpieces, it cannot be quickly removed afterwards, so there is room for improvement. Utility Model Content

[0004] The main purpose of the utility model is to provide a projector with stable placement, aiming to solve the technical problem of unstable placement of the projector.

[0005] To achieve the above-mentioned object, the present invention provides a stably placed projector, the projector comprising:

[0006] Projection housing;

[0007] a control module disposed within the projection housing, the control module including a light source assembly and an optical path assembly cooperating with the light source assembly, a first heat dissipation fan and a second heat dissipation fan being respectively disposed on both sides of the optical path assembly, and a first heat dissipation channel being formed between the first heat dissipation fan, the optical path assembly, and the second heat dissipation fan;

[0008] At least one stabilizing component is disposed in the first heat dissipation channel, and the at least one stabilizing component is located below the optical path component, and the stabilizing component includes an adsorption member capable of connecting the interior and exterior of the projection housing;

[0009] Among them, under the suction action of the first heat dissipation fan and the second heat dissipation fan, the adsorption component is affected by the air pressure of the first heat dissipation channel, so that the adsorption component located outside the projection shell is stably adsorbed on the plane placed at the bottom of the projection shell.

[0010] In the technical solution provided by the present invention, a stabilizing component is provided in the first heat dissipation channel, and the stabilizing component is also located below the optical path component, so that when the heat dissipation process is carried out in the first heat dissipation channel, the stabilizing component will also be affected accordingly. Specifically, since the stabilizing component includes an adsorption component that can connect the inside and outside of the projection shell, the adsorption component is affected by the change of the air pressure value of the first heat dissipation channel under the cooperation of the first heat dissipation fan and the second heat dissipation fan in the first heat dissipation channel, so that the adsorption component located outside the projection shell can be stably adsorbed to the plane placed at the bottom of the projection shell, thereby improving the stability between the projector and the plane. The above design utilizes the traditional projector heat dissipation principle, further improves the stability of the projector placement, realizes the effect of one structure with two uses, and has extremely strong sophistication. Secondly, the design structure is simple, and there is no need to disassemble the projector when moving it to another place. You only need to turn off the projector, which greatly improves the convenience of user use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] This utility model provides a projector that is placed stably, please refer to Figure 1-Figure 5The projector includes a projection housing 1, a control module 2 arranged inside the projection housing 1, at least one stabilization component 3 and other structural elements that meet the normal operation of the projector, such as a lens component 4 and a lens cover 5 that covers the lens to prevent dust. The control module 2 includes a light source component 21 and an optical path component 22 that cooperates with the light source component 21. A first heat dissipation fan 23 and a second heat dissipation fan 24 are respectively provided on both sides of the optical path component 22. A first heat dissipation channel is formed between the first heat dissipation fan 23, the optical path component 22 and the second heat dissipation fan 24. As for the stabilization component 3, it is arranged in the first heat dissipation channel, and at least one stabilization component 3 is located below the optical path component 22. Component 3 includes an adsorption component 32 that can connect the inside and outside of the projection shell 1. Under the suction action of the first heat dissipation fan 23 and the second heat dissipation fan 24, the adsorption component 32 is affected by the air pressure of the first heat dissipation channel, so that the adsorption component 32 located outside the projection shell 1 is stably adsorbed with the plane placed at the bottom of the projection shell 1, thereby improving the stability between the projector and the plane. The above design utilizes the heat dissipation principle of the projector, further improves the stability of the projector placement, realizes the effect of one structure with two uses, and has extremely strong practicality. Secondly, this design has a simple structure. When moving the projector to another place, there is no need to disassemble it. You only need to turn off the projector, which greatly improves the convenience of user use.

[0028] For Stabilization Component 3, please refer to Figure 4 and Figure 5 In this embodiment, there are two stabilizing components 3, and the stabilizing components 3 also include a stabilizing shaft structure 31. The stabilizing shaft structure 31 is arranged at the bottom shell 12 inside the projection shell 1, and the vertical section of the stabilizing shaft structure 31 is "T"-shaped. The stabilizing shaft structure 31 has an adsorption channel 311 connecting the inside and outside of the projection shell 1. The shape of the stabilizing shaft structure 31 is convenient for the built-in adsorption component 32 and stabilizes the position of the adsorption component 32 to prevent the adsorption component 32 from escaping from the adsorption channel 311.

[0029] Specifically, the outside of the adsorption component 32 is built into the adsorption channel 311, and the top of the adsorption component 32 protrudes from the stabilizing shaft structure 31, and the bottom of the adsorption component 32 protrudes from the bottom of the projection shell 1. It should be noted that in this embodiment, the outside of the adsorption component 32 is fixed to the inner wall surface of the adsorption channel 311, for example, by bonding. Secondly, the bottom end of the adsorption component 32 is truncated cone-shaped, and the bottom end of the adsorption component 32 is mainly used for adsorption with the plane.

[0030] Furthermore, the adsorption member 32 includes a rubber structure, that is, the adsorption member 32 is elastic and can adapt to a plane with a certain degree of roughness, which greatly expands the placement environment of the projector.

[0031] In other embodiments, the number of the stabilizing components 3 can be four, five, etc., as long as the stabilizing components 3 are below the optical path component 22 and the pressure at the bottom of the adsorption member 32 can be reduced to the level of the adsorption surface.

[0032] In this embodiment, please refer to Figure 3 and Figure 4 The optical path component 22 includes a display screen 221, a reflector 222 and a front mirror 223 arranged in sequence. The display screen 221 and the reflector 222, as well as the interval between the reflector 222 and the front mirror 223 constitute part of the first heat dissipation channel. This design facilitates heat dissipation of the display screen 221, the reflector 222 and the front mirror 223.

[0033] As for the light source assembly 21 , it belongs to the existing technology and should be known to those skilled in the art, so it will not be elaborated here.

[0034] Furthermore, the first heat dissipation fan 23 includes a first air inlet and a first air outlet, and an air guide 25 is arranged between the first air outlet and the side of the optical path component 22. The air guide 25 is mainly arranged to guide the air blown out by the first heat dissipation fan 23 into the optical path component 22, that is, the gap between the display screen 221 and the reflector 222, and the reflector 222 and the front mirror 223, to take away the heat generated by them, thereby realizing the heat dissipation function.

[0035] As for the air guide member 25, in this embodiment, the air guide member 25 is a box-shaped structure with an arc-shaped outer periphery. One end of the air guide member 25 is connected to the first air outlet, and the other end is connected to the side of the optical path component 22, thereby guiding the wind blown out by the first heat dissipation fan 23 to the interior of the optical path component 22.

[0036] In this embodiment, the channel through which the first air inlet of the first heat dissipation fan 23 draws in air from outside the projector is the second heat dissipation channel, which is mainly used for the first heat dissipation fan 23 to absorb air and generate wind force to dissipate heat from the optical path component 22 .

[0037] As for the second heat dissipation fan 24, it includes a second air inlet and a second air outlet. The second air inlet is located on the side of the optical path component 22 away from the first air outlet. A heat conductor 26 is also provided inside the projection housing 1. The heat conductor 26 is located on the air outlet path of the second air outlet. The above arrangement mainly enables the second heat dissipation fan 24 to absorb the hot air passing through the first heat dissipation channel, and then the second heat dissipation fan 24 blows out from the second air outlet, and transfers the heat to the outside of the projector through the heat conductive sheet, thereby realizing heat dissipation of the entire projector.

[0038] The heat conducting member 26 includes a plurality of heat conducting sheets distributed in an array, and this design is used to improve the heat conduction efficiency.

[0039] In this embodiment, the projection housing 1 is provided with an air inlet 13 and an air outlet 14. Specifically, the first air inlet on the first heat dissipation fan 23 draws air through the air inlet 13, that is, the channel between the first air inlet and the air inlet 13 constitutes the above-mentioned second heat dissipation channel. As for the air outlet 14, it is located on the side of the heat conductor 26 away from the second air outlet to circulate the hot air to the outside of the projector, thereby realizing the heat dissipation process of the entire projector.

[0040] In fact, please refer to Figure 2 In order to ensure that the heat inside the projector is dissipated more completely, a dustproof frame 6 is provided between the top of the control module 2 and the top shell 11 inside the projection shell 1. This setting can prevent external dust from entering the projection shell 1 and can further seal the first heat dissipation channel, that is, ensure that the heat inside the projection shell 1 is further dissipated with the wind flow. At the same time, this design also further ensures that the air pressure inside the adsorption component 32 is reduced.

[0041] For further description of the working principle of how this projector improves placement stability, please refer to Figure 3 and Figure 4 First, the first heat dissipation fan 23 draws air from the air inlet 13, that is, passes through the second heat dissipation channel, and then is discharged from the first air outlet. The wind enters the optical path component 22 through the air guide 25. During this process, the second heat dissipation fan 24 is also running. The second heat dissipation fan 24 draws hot air carrying heat through the second air inlet, and then discharges it through the second air outlet. The hot air passes through the heat conductor 26 and is discharged from the air outlet 14 to the outside of the projector. At this point, the heat dissipation process of the projector is completed. Among them, when the second heat dissipation fan 24 is sucking air, the airflow generated by part of the first heat dissipation channel in the optical path component 22 will take away the gas of the adsorption component 32, thereby reducing the internal air pressure of the adsorption component 32, so that the adsorption component 32 is firmly adsorbed to the plane. For details, please refer to Figure 5 It should be noted that L represents the direction of hot air flow in the first heat dissipation channel, and M represents the direction in which the gas in the adsorption member 32 is taken away. This design utilizes the heat dissipation function of the projector to further achieve the stability of the projector placement. No additional auxiliary structure is required to fix the projector, which saves costs and is convenient for users to use. Moreover, this design does not require users to assemble and disassemble, and is extremely practical.
