Description

Technical Field

[0001] The utility model relates to the technical field of projectors, in particular to a projector with a convenient control wheel. Background Art

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals.

[0003] Traditional projectors require users to manually turn a wheel to adjust the focus structure. For placed projectors, manual re-focusing is often required due to changes in the distance between the projector and the screen or projection wall. Manually turning the wheel to focus may result in excessive or slight turning of the wheel due to poor control of the force, resulting in out-of-focus and inadequate focus. Therefore, in order to meet the projection clarity required by the user, the user needs to repeatedly adjust the wheel. If the user's hand is suspended above the wheel and the finger is used to adjust the wheel, the arm will easily feel tired or powerless. If the user's palm rests on the surface of the projection shell, it will often be blocked by the adjustment port on the projection shell for installing the wheel, thereby damaging the user's palm. The above problems will make it difficult for the user to adjust the wheel, and thus inconvenient to adjust the focus of the projector. Therefore, there is room for improvement.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] This utility model provides a projector that is easy to control the wheel, please refer to Figure 1-Figure 3 The projector includes a projection shell 1, a control module 3 arranged inside the projection shell 1, at least one arc-shaped pad 2 and other structural elements that meet the normal operation of the projector, such as a heat sink. The side of the projection shell 1 is provided with a mirror port pipe 11 that is connected to the inside of the projection shell 1. The mirror port pipe 11 is installed with a lens assembly 111. The top of the projection shell 1 is provided with an adjustment port 12 located above the lens assembly 111. A wheel 1111 is provided on the outside of the lens assembly 111. This arrangement allows the user's hand to pass through the adjustment port 12 and manually rotate the wheel 1111 to adjust the focal length of the lens assembly 111. As for the arc-shaped pad 2, at least one arc-shaped pad 2 is fixed / integrally molded on the top of the projection shell 1, and at least one arc-shaped pad 2 is arranged around the adjustment port 12.

[0024] Among them, when the user manually rotates the wheel 1111, at least one arc-shaped pad 2 supports the user's palm, so that the user can manually rotate the wheel 1111 through the adjustment port 12, and then adjust the focal length of the lens assembly 111. The above-mentioned setting supports the user's palm through at least one arc-shaped pad 2, thereby avoiding the user's arm from being suspended, reducing the discomfort and weakness of the user's arm. At the same time, the arc-shaped pad 2 also conforms to the ergonomic design of the user's palm, and will not cause diaphragmatic pain in the user's palm, thereby allowing the user to conveniently rotate the wheel.

[0025] The structural elements involved above are described in detail below.

[0026] In this embodiment, please refer to Figure 1 There are two arc-shaped pads 2, which are respectively located on two opposite sides of the opening end of the adjustment port 12, and one arc-shaped pad 2 is located above the end of the lens assembly 111. For the convenience of description, the two arc-shaped pads 2 are respectively named as the first arc-shaped pad 21 and the second arc-shaped pad 22, wherein the first arc-shaped pad 21 is located above the end of the lens assembly 111, and the second arc-shaped pad 22 is located above the other end of the lens assembly 111. The above design enables the user to stand on the side of the projection shell 1 or on the other side opposite to the lens port channel, and the user can support the user's palm through the second arc-shaped pad 22, so that the user can manually rotate the wheel 1111 for a long time.

[0027] In other embodiments, the number of the arc-shaped pads 2 is three or four, etc. Specifically, the arc-shaped pads 2 can support the user's palm, making it convenient for the user to manually rotate the wheel 1111.

[0028] In this embodiment, the arc-shaped pad 2 is made of an elastic material, such as rubber. The arc-shaped pad 2 made of this material can cushion the palm and improve the comfort of the palm.

[0029] For further information, please refer to Figure 1 and Figure 2 The bottom of the projection shell 1 is provided with a mounting seat 4, and the bottom of the projection shell 1 is also provided with an anti-collision pad 5, wherein the anti-collision pad 5 is located below the connection between the mirror port pipe 11 and the outside, and the side of the anti-collision pad 5 is fixedly connected to the side of the mounting seat 4. The anti-collision pad 5 is designed mainly to prevent the outside of the mirror port pipe 11 arranged on the side of the projection shell 1 from being collided with other structures placed on the ground, or being affected by other external forces during the placement of the projector, thereby causing damage to the mirror port pipe 11.

[0030] In this embodiment, the outer portion of the anti-collision pad 5 is arc-shaped. This design not only achieves an anti-collision effect, but also, when combined with the first arc-shaped pad 21, can protect the mirror port pipe 11 on the side of the projection shell 1, thereby preventing the top and bottom of the mirror port pipe 11 from being damaged due to external collisions, thereby affecting the normal operation of the lens assembly 111. Among them, due to the setting of the adjustment hole 12, the top protection ability of the mirror port pipe 11 located on the side of the projection shell 1 is relatively weak. Therefore, the design of the first arc-shaped pad 21 makes up for the defect of weak protection ability of the top of the mirror port pipe 11, and further improves the firmness of the projector.

[0031] Furthermore, the anti-collision pad 5 includes a rubber structure, so that it has a buffering effect.

[0032] In this embodiment, please refer to Figure 1 and Figure 2 The projection shell 1 has two opposite ends, the two end parts are the first end and the second end, the horizontal distance between the mirror port pipe 11 and the first end is smaller than the horizontal distance between the mirror port pipe 11 and the second end. This setting is mainly to facilitate the user to rotate the wheel 1111 without stretching his arm, thereby reducing the discomfort of the user's arm. Secondly, the first end is divided into two parts, one part is provided with a heat dissipation hole 6, and the other part is provided with a mounting plate 7. The mounting plate 7 and the mirror port pipe 11 are opposite and parallel to each other, so that when the user stands on the side of the projection shell 1, the heat dissipated by the heat dissipation hole 6 will not affect himself due to the setting of the mounting plate 7, thereby further improving the comfort of the user in adjusting the focal length of the projector.

[0033] Furthermore, the connection between the side of the projection shell 1 and the other side is an arc surface, which means that the connection between the side parts of the projection shell 1 is an arc surface. This arc surface setting can prevent the user from being hit by the connection between the side parts of the projection shell 1 when passing by the projector in life and causing damage. Secondly, this design can also prevent the user's arms from being blocked by the connection between the side parts when moving the projector, thereby causing bruises and scratches.

[0034] In essence, in order to ensure that the projector can be fixed more stably after being placed in the corresponding position, the bottom of the projection shell 1 is also provided with a shock-proof support angle 41. The shock-proof support angle 41 is made of rubber and mainly plays a shock-proof and buffering role. When the placement is unstable or uneven, this design can ensure the stability of the projector.

[0035] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
