Description
Technical Field
[0001] This utility model relates to the field of projector technology, specifically a projector that utilizes head and limb rotation to achieve multi-angle projection. Background Technology
[0002] With the continuous development of projection technology, projectors have been widely used in homes, offices, schools, and entertainment venues, becoming an important tool for displaying videos and images. Existing projectors typically suffer from a relatively fixed projection direction, which can be addressed in two ways:
[0003] Method 1: The projection direction can only be adjusted by placing the object in different positions, and it often does not have the function of changing the projection direction in the vertical direction.
[0004] Method 2: Add a gimbal-type bracket, and adjust the projection direction by adjusting the angle of the bracket up, down, left, and right.
[0005] The limitations of the first method are particularly prominent in certain application scenarios. For example, when projection needs to be made at different angles or in different directions, it is often necessary to adjust the placement of the projector. This is not only cumbersome to operate, but also limits the flexibility of projection and the diversity of application scenarios.
[0006] The limitations of the second method are that the bracket is more expensive, the adjustable angle is limited, it is easily restricted by the power cord, and it can easily block the air inlet and outlet, affecting the heat dissipation efficiency of the projector and thus its lifespan.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-8 This utility model discloses a projector that utilizes head and limb rotation to achieve multi-angle projection, including a body 1 and a projection engine 2. A head adjustment component 11 is movably disposed at one end of the top of the body 1. The top of the head adjustment component 11 is cylindrical and used to connect to the projection engine 2. At least one limb adjustment component 12 is movably disposed on each side of the body 1, and the number of limb adjustment components 12 is at least four. A decorative component 17, which is tail-shaped, is disposed at the end of the body 1 away from the head adjustment component 11. The body 1, head adjustment component 11, limb adjustment component 12, and tail decorative component form the shape of a small animal, so that the product can not only support the projection engine 2 but also be used as a decorative item. It is aesthetically pleasing, and with the four adjustable limb adjustment components 12 and the head adjustment component 11, the small animal can be posed in different postures. At the same time, the projection angle of the projection engine 2 can be adjusted, making it more convenient to use.
[0030] By adding a rotatable head adjustment component 11 and limb adjustment component 12 to the main body 1, and through a precise mechanical connection and transmission structure, the head and limbs can rotate freely in multiple directions. This design allows the projector to achieve an all-around projection effect by adjusting the rotation angle of the head and limbs without changing the overall placement. Users can freely adjust the projection direction according to their actual needs and switch between various projection modes such as rear projection, top projection, and side projection. This not only meets the projection needs in different scenarios but also improves the flexibility and convenience of projection.
[0031] This product is particularly suitable for 3D image projection technology. By adjusting the rotation angle of the head and limbs, it can synchronously display virtual world content with real-world objects, creating a visually impactful and artistically appealing 3D dynamic image effect. Its reasonable structural design makes it easy to operate and maintain. Users can easily adjust the projection direction with simple operations. Furthermore, the projector is relatively easy to maintain, reducing operating costs.
[0032] Specifically, the top of the head adjustment component 11 is provided with a fixing bone 13, and the fixing bone 13 is provided with at least one stud 133 for screwing and fixing the projection optical engine 2. One side of the fixing bone 13 is provided with a foolproof straight edge 131, the other side is provided with a foolproof groove 132, and the remaining two sides are arc-shaped. The foolproof design makes it easier to assemble the projection optical engine 2. After the projection optical engine 2 is connected to the head adjustment component 11, it can rotate at any angle in the horizontal direction, thereby realizing the angle adjustment in the horizontal direction and realizing the horizontal side projection of the projected image.
[0033] Specifically, the bottom end of the head adjustment component 11 is arc-shaped, and the two sides of the bottom end are flat. The bottom end and the top end of the head adjustment component 11 form a 45° angle. The rotation angle of the head adjustment component 11 inside the body 1 is 0°-90°, thereby achieving a 45° upward projection and a 45° downward projection (45° is the angle to ensure the lowest viewing effect). The arc-shaped design of the bottom end of the head adjustment component 11 makes the rotation more flexible and smooth.
[0034] Specifically, the head adjustment component 11 has a fixing hole 14 inside, and the body 1 has a hinge component 15 that is movably connected to the fixing hole 14 inside. The fixing hole 14 has a rubber ring inside to increase rotational resistance. The fixing hole 14 can rotate relative to the hinge component 15 to adjust the angle of the head adjustment component 11.
[0035] Specifically, each side of the body 1 is provided with at least one movable slot 16, and the movable slot 16 is provided with at least two positioning posts 161. The limb adjustment component 12 is provided with two positioning slots 121 that are respectively fitted with the two positioning posts 161. The movable slot 16 is used to install the limb adjustment component 12. After the positioning slots 121 and the positioning posts 161 are connected, they are locked by two screws.
[0036] Specifically, the movable groove 16 is fixedly provided with an arc-shaped hole 162 located outside the positioning post 161. A rotating card 122 with one end extending into the arc-shaped hole 162 is fixedly provided on one side of the limb adjustment component 12. The rotating card 122 is inserted into the arc-shaped hole 162. As the limb adjustment component 12 rotates, the rotating card 122 moves with it inside the arc-shaped hole 162. The arc-shaped hole 162, together with the rotating card 122, restricts the rotation angle of the limb adjustment component 12, thus ensuring the stability of the body 1.
[0037] Specifically, a rubber ring 123 is fitted on one side of the limb adjustment component 12. One side of the rubber ring 123 is in contact with one side of the movable groove 16. The rubber ring 123 and the movable groove 16 are tightly fitted, which increases the rotational resistance of the limb adjustment component 12 and achieves the effect of rotational suspension.
[0038] In summary, this projector, which utilizes head and limb rotation to achieve multi-angle projection, enables omnidirectional and multi-angle projection without changing the overall placement of the projector by adjusting the rotation angle of the head and limb adjustment components 11 and 12, through an adjustable head adjustment component 11 and multiple limb adjustment components 12. Furthermore, the animal-shaped design not only improves the projector's flexibility and versatility in application scenarios but also breaks through the limitations of the traditional projector's monotonous design, allowing it to be used as a decorative item with an aesthetically pleasing appearance and greater ease of use.
