Description

Technical Field

[0001] This utility model relates to the field of film and television robotic arms, and in particular to a lightweight and portable film and television robotic arm. Background Technology

[0002] In the traditional film and television shooting industry, robotic arms are a relatively new type of film and television shooting equipment. Due to their unique advantages such as good camera stability, ability to complete smooth and complex movements, and repeatable motion trajectories, the application frequency of robotic arms in film and television is increasing. However, because traditional robotic arms in film and television are simply modified from six-axis industrial robots, they inevitably inherit the disadvantages of six-axis industrial robots, such as large weight, large size, and difficulty in transportation. Moreover, the deployment process of traditional robotic arms after being transported to the shooting location is very cumbersome and time-consuming. All these factors limit their application scenarios. Utility Model Content

[0003] The purpose of this invention is to provide a lightweight and portable film and television robotic arm, which solves the problems of traditional film and television robotic arms being bulky, difficult to transport, and having a complex deployment process, thereby lowering the threshold for using film and television robotic arms and empowering more film and television shooting application scenarios.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight portable film and television robotic arm, including a box body, a lifting opening on the top plate of the box body and a hinged cover, and a robotic arm body that is completely housed inside the box body and can be raised and lowered to pass through the lifting opening.

[0005] Preferably, the bottom plate of the box is equipped with brake casters, and the side of the box is equipped with a support structure.

[0006] Preferably, the robotic arm body includes a base and an arm portion, the arm portion having a hollow structure.

[0007] Preferably, the base plate is provided with a vertically oriented track, the track is fitted with a body mounting plate, and the body mounting plate is sleeved with the track through a linear bearing, and the robot body is mounted on the body mounting plate.

[0008] Preferably, the bottom plate is provided with a bottom latch that cooperates with and locks to the main body mounting plate, and the lower part of the top plate is provided with a top latch that cooperates with and locks to the main body mounting plate.

[0009] Preferably, the support structure includes a leg mounting base installed on the side of the housing, the leg mounting base is equipped with an Alley tooth by a hand-tightening screw, the Alley tooth is connected to a support leg, and the support body is connected to a universal foot cup.

[0010] Preferably, the box also contains an electrical control box, and the part of the box where the electrical control box is installed is the door.

[0011] The technical effects of this utility model are as follows:

[0012] 1. The integrated base design allows for easy storage and transportation, and can be placed in the trunk of a car. It facilitates convenient storage and deployment, making it easy to use and dismantle. This solves the problems of traditional film and television robotic arms being bulky, difficult to transport, and having a complex deployment process, thus lowering the barrier to entry for using film and television robotic arms and empowering more film and television shooting application scenarios.

[0013] 2. The arm body is made into a hollow structure, thereby achieving a lightweight design of the robotic arm and reducing its weight. This makes it easier to store and transport. The robotic arm used in film and television shooting only needs to support the weight of the shooting equipment, which generally does not exceed 15kg. Even after being lightweight, it will not affect film and television shooting. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] like Figure 1-3As shown, this embodiment of a lightweight portable film and television robotic arm includes a housing 13. The top plate 11 of the housing 13 has a lifting opening, which is usually matched with an opening and closing cover. The robotic arm body 1 is completely stored inside the housing 13 and can be raised and lowered to pass through the lifting opening.

[0022] When not in use, the robotic arm in this embodiment is completely stored inside the housing 13, which measures 45cm*40cm*82cm. This allows it to be easily placed in the trunk of a car, making it convenient for film enthusiasts to carry. When needed, the housing 13 is first removed from the trunk and moved to the desired location. Then, the opening and closing cover is opened, and the robotic arm is pulled out from the lifting port (manual, electric, or pneumatic lifting can be used). The camera to be used for filming is then mounted on the robotic arm, and the camera movement is then used to shoot. This robotic arm solves the problems of traditional robotic arms being bulky, difficult to transport, and having complex deployment processes, lowering the barrier to entry for using robotic arms and enabling more diverse film and television shooting applications.

[0023] In a further optimization of the above embodiment, the robotic arm body 1 includes a base and an arm body. The arm body has a hollow structure and is made of lightweight materials such as carbon fiber tubes and aluminum. It can meet the weight bearing requirements of photography without affecting the video recording, and at the same time further reduces the overall weight.

[0024] In a further optimization of the above embodiment, a brake caster 3 is installed on the lower part of the bottom plate 4 of the housing 13, and a support structure is installed on the side of the housing 13. This optimized design allows the housing to be pushed to the desired position using the brake caster 3 at suitable shooting locations, reducing the difficulty of handling. The brake caster 3 then uses its built-in braking mechanism for braking, and the support structure provides further support, ensuring the overall stability of the housing 13.

[0025] Example 2

[0026] like Figure 2-3 As shown, compared to Embodiment 1, this embodiment specifically discloses the lifting structure of the robotic arm, specifically: a vertically oriented track 7 is provided on the base plate 4, the track 7 is fitted with a main body mounting plate 2, and the main body mounting plate 2 is sleeved with the track 7 through a linear bearing 6, the robotic arm body 1 is mounted on the main body mounting plate 2, a bottom latch 3 is provided on the base plate 4 that cooperates with and touches the main body mounting plate 2 to lock, and a top latch 12 is provided at the lower part of the top plate 11 that cooperates with and touches the main body mounting plate 2 to lock.

[0027] Compared to Embodiment 1, in the storage state, the main mounting plate 2 and the bottom latch 3 are locked together. In the working state, the photographer lifts the entire robotic arm upwards, thus the main mounting plate 3 overcomes the locking force of the bottom latch 3 (the latch is generally an elastic locking structure). Then, through the cooperation of the linear bearing 6 and the track 7, the main mounting plate 3 and the robotic arm on it rise together until they contact the top latch 12 and are locked by the top latch 12. Through the design of the upper and lower latches, locking in both the storage and working states can be achieved, further simplifying the operation of the photographer.

[0028] Example 3

[0029] like Figure 2 and Figure 4 As shown, compared to Embodiment 1, this embodiment defines a support structure, which includes a leg mounting base 16 installed on the side of the housing 13. The leg mounting base is equipped with an Alley tooth 17 by a hand-tightening screw 10. The Alley tooth 17 is connected to a support leg 9, and the support body 9 is connected to a universal foot cup 8.

[0030] For handling purposes, the outrigger mounting base 16 and the entire support structure can be installed on the housing 13 or disassembled. In operation, the support structure is installed on the housing 13. Depending on the terrain, first loosen the locking screw 10 to the Alley tooth 17, so that the two Alley teeth 2 are separated, with one connected to the outrigger mounting base 16 and the other connected to the support leg 9. After adjusting the angle of the support leg 9, make the two Alley teeth 2 mesh again and then tighten them with the screw 10. The universal foot cup 8 contacts the ground, thus enabling the support structure to support the housing 13. The support structure is generally set in three sets and arranged in a triangle to ensure good support effect.

[0031] like Figure 1-3 As shown, an electrical control box 15 is also provided inside the box 13, and the part of the box 13 where the electrical control box 15 is installed is the opening and closing door 14.

[0032] An electrical control box 15 is installed inside the housing 13, and an opening and closing door is provided. In this way, the operation of the robotic arm can be controlled through the electrical control box to achieve the shooting and camera movement of the required trajectory.
