Description
Technical Field
[0001] This utility model relates to the field of motor connecting arm technology, specifically to a compact integrated motor connecting arm. Background Technology
[0002] The compact motor-integrated connecting arm is a device that highly integrates the motor and the connecting arm. It can mount camera equipment on the connecting arm and features small size, light weight, and high performance. It is widely used in film and television production, photography and other fields.
[0003] The Chinese utility model patent with authorization announcement number "CN205004856U" is specifically "an integrated motor connecting arm". It includes a connecting rod with a fixed seat and a connecting cover at both ends. A motor stator is fixed on the fixed seat, and the motor stator has a varnished wire winding. It also includes a rotating part of the motor, which is matched and installed with the motor stator. The rotating part includes an integrally rotating motor housing, a magnet, an end cover, and a motor shaft. The magnet is arranged around the inner wall of the motor housing. The end cover is located at one end of the motor housing and the motor shaft is fixed on the end cover. A through hole is provided in the middle of the motor stator, and one end of the motor shaft passes through the through hole and is rotatably connected to the fixed seat. The magnets on the motor housing and its inner wall are matched and located on the outer periphery of the motor stator. The end cover is used for installation and connection with the connecting cover of another connecting arm.
[0004] The aforementioned device consists of a horizontally positioned connecting cover within the gimbal for controlling heading, and a fixed base and connecting rod inclined relative to each other. The fixed base is vertically positioned within the gimbal to control roll direction. A motor drives the connecting rod of the connecting arm to rotate and adjust the angle with the fixed base, further mounting the camera equipment on the fixed base. This allows the camera equipment to be supported and controlled for lateral rotation adjustment via the connecting arm. However, there are some drawbacks: while the connecting rod of the connecting arm rotates laterally via a motor, which in turn drives the fixed base to rotate laterally, the motor can only adjust the lateral rotation direction of the connecting rod and cannot adjust its longitudinal rotation. This ultimately limits the range of motion of the camera equipment on the fixed base, restricting its shooting angle and coverage area. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a compact integrated motor connecting arm, which can effectively solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a compact integrated motor connecting arm, including a first connecting rod, a fixed connecting rod, and a longitudinal rotating connecting rod. A fixed cover is fixedly installed on one side of the lower end of the first connecting rod. A second outer shell is fixedly installed on one end of the fixed connecting rod. A longitudinal adjustment component is provided on the other end of the fixed connecting rod. The longitudinal adjustment component is used to adjust the longitudinal rotation of the longitudinal rotating connecting rod. A fixed seat is fixedly installed on one end of the longitudinal rotating connecting rod. The longitudinal adjustment assembly includes a first fixing plate and a second fixing plate, and one side of each of the first fixing plate and the second fixing plate is fixedly installed on one side of the fixed connecting rod.
[0007] Furthermore, a fixing sleeve is fixedly sleeved inside one end of the first fixing plate and the second fixing plate, a fixing shaft is fixedly sleeved inside the fixing sleeve, and an inner ring is fixedly sleeved outside the fixing shaft.
[0008] Furthermore, an outer ring sleeve is fitted on the outer side of the inner ring sleeve, and multiple balls are movably fitted between the outer ring sleeve and the inner ring sleeve. Connecting pieces are fixedly installed at both ends of the outer ring sleeve, and the interior of the connecting pieces is sleeved through the outer side of the fixed shaft.
[0009] Furthermore, the outer wall of the outer ring sleeve is fixedly sleeved inside one end of the longitudinal rotating connecting rod, and a first gear is fixedly installed on one side of one of the connecting pieces of the outer ring sleeve, with the inner rotating sleeve of the first gear being sleeved on the outer side of the inner ring sleeve.
[0010] Furthermore, a second gear is meshed with the outer side of the first gear, a rotating rod is fixedly installed at one end of the second gear, an electric motor is fixedly installed at one end of the rotating rod, and a socket frame is fixedly installed at one end of the electric motor. The socket frame is fixedly fitted inside the outer wall of the fixed housing, and a slot is opened inside the outer wall of one of the fixed housings, with the socket frame located inside the slot of the fixed housing.
[0011] Furthermore, a first housing is fixedly installed at the upper end of the first connecting rod, a motor is fixedly installed inside the first housing, the output end of the motor is fixedly installed at one end of the second housing, a bearing sleeve is fixedly sleeved on the inner wall of the first housing, and the outer wall of the bearing sleeve is fixedly sleeved on the inner wall of the second housing.
[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model uses a longitudinal adjustment component and a longitudinal rotating connecting rod. Powered by an electric motor and driven by gear meshing, the outer ring sleeve rotates around the inner ring sleeve and the fixed shaft, thereby enabling the longitudinal rotating connecting rod and the camera equipment on the fixed base to complete the longitudinal angle adjustment. Compared with the traditional method where the connecting rod of the connecting arm rotates laterally via a motor, thus causing the fixed base to rotate laterally synchronously, this method avoids limiting the range of motion of the camera equipment on the fixed base, thus preventing the camera equipment from being restricted in its shooting angle and coverage area.
[0013] 2. At the same time, the first and second fixing plates, the fixing sleeve and the fixing shaft can provide support for the longitudinal adjustment component and the longitudinal rotating connecting rod, and prevent the longitudinal rotating connecting rod from shaking during the rotation adjustment process.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] The present invention will be further described below with reference to the embodiments.
[0019] Example 1: Reference Figures 1 to 4 This is the first embodiment of the present utility model, which discloses a compact integrated motor connecting arm, including a first connecting rod 1, a fixed connecting rod 2 and a longitudinal rotating connecting rod 3. A fixed cover 5 is fixedly installed on one side of the lower end of the first connecting rod 1. A second outer shell 7 is fixedly installed on one end of the fixed connecting rod 2. A longitudinal adjustment component 6 is provided on the other end of the fixed connecting rod 2. The longitudinal adjustment component 6 is used to adjust the longitudinal rotation of the longitudinal rotating connecting rod 3. A fixed seat 4 is fixedly installed on one end of the longitudinal rotating connecting rod 3. First, the entire connecting arm structure is fixed in the gimbal mounting position by the fixed cover 5 at the lower end of the first connecting rod 1. The longitudinal adjustment assembly 6 includes a first fixed plate 61 and a second fixed plate 62. One side of the first fixed plate 61 and the second fixed plate 62 are fixedly installed on one side of the fixed connecting rod 2. A fixed sleeve 63 is fixedly sleeved inside one end of the first fixed plate 61 and the second fixed plate 62. A fixed shaft 69 is fixedly sleeved inside the fixed sleeve 63. An inner ring sleeve 67 is fixedly sleeved outside the fixed shaft 69. An outer ring sleeve 66 is sleeved outside the inner ring sleeve 67. Multiple balls are movably sleeved between the outer ring sleeve 66 and the inner ring sleeve 67. Connecting pieces 68 are fixedly installed at both ends of the outer ring sleeve 66. The interior of the connecting pieces 68 is sleeved through the outside of the fixed shaft 69.
[0020] The outer wall of the outer ring sleeve 66 is fixedly fitted inside one end of the longitudinal rotating connecting rod 3. A first gear 610 is fixedly installed on one side of one of the connecting pieces 68 of the outer ring sleeve 66. The inner side of the first gear 610 is rotatably fitted on the outer side of the inner ring sleeve 67. A second gear 611 is meshed with the outer side of the first gear 610. A rotating rod 612 is fixedly installed at one end of the second gear 611. An electric motor 613 is fixedly installed at one end of the rotating rod 612. A socket frame 65 is fixedly installed at one end of the electric motor 613. The socket frame 65 is fixedly fitted inside the outer wall of the fixed housing 63. A slot 64 is opened inside the outer wall of one of the fixed housings 63. The socket frame 65 is located inside the slot 64 of the fixed housing 63.
[0021] In use, when the longitudinal rotation angle of the camera equipment on the fixed base 4 needs to be adjusted by the fixed connecting rod 2 and the longitudinal rotating connecting rod 3 of the connecting arm, the first fixed plate 61 and the second fixed plate 62 are connected to the fixed connecting rod 2 to form a stable support frame. The fixed sleeve 63 is fixed at one end of the two fixed plates. The internal fixed shaft rod 69 is the core support shaft. The electric motor 613 is started, and its output end drives the rotating rod 612 to rotate. The second gear 611 at the other end of the rotating rod 612 rotates accordingly. Since the second gear 611 meshes with the first gear 610, the rotation of the second gear 611 will drive the first gear 610 to rotate around the outer side of the inner ring sleeve 67. The first gear 610 is fixed on the connecting piece 68 near the electric motor 613. The connecting piece 68 is fixed to the outer ring sleeve 66. Therefore, the rotation of the first gear 610 will synchronously drive the outer ring sleeve 66 to rotate around the inner ring sleeve 67 with the fixed shaft 69 as the axis, thereby realizing the longitudinal angle adjustment of the longitudinal rotating connecting rod 3 of the connecting arm. This avoids the limited range of motion of the camera equipment on the fixed base 4, which would restrict the shooting angle and coverage of the camera equipment.
[0022] Example 2: Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a first outer shell 8 is fixedly installed on the upper end of the first connecting rod 1, a motor 81 is fixedly installed inside the first outer shell 8, the output end of the motor 81 is fixedly installed on one end of the second outer shell 7, a bearing sleeve 82 is fixedly sleeved on the inner wall of the first outer shell 8, and the outer wall of the bearing sleeve 82 is fixedly sleeved on the inner wall of the second outer shell 7.
[0023] In use, when it is necessary for the second outer shell 7 to rotate relative to the first outer shell 8, the motor 81 fixedly installed inside the first outer shell 8 is started. The output end of the motor 81 will transmit power to the second outer shell 7 fixedly connected to it, causing the second outer shell 7 to start rotating. At the same time, since the outer wall of the bearing sleeve 82 fixedly sleeved on the inner wall of the first outer shell 8 is fixedly sleeved on the inner wall of the second outer shell 7, the outer ring of the bearing sleeve 82 will rotate together with the second outer shell 7 during the rotation of the second outer shell 7. The first connecting rod 1 of the connecting arm supports the first outer shell 8, the motor 81, the second outer shell 7 and other components.
[0024] The remaining structure is the same as that in Example 1.
[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
