Description

Technical Field

[0001] This utility model relates to the field of swing arm mechanical technology, and in particular to a vertical swing arm system. Background Technology

[0002] When a swing arm mechanism needs to support a weight exceeding 100kg, a high-power motor is typically used to support the reciprocating swing arm. However, because the resistance that the vertical swing arm mechanism needs to overcome differs between its downward and upward strokes, and this difference increases with the weight of the object being supported, using the same motor to support the same weight results in a greater speed difference between the upward and downward strokes. This makes the vertical swing arm mechanism less effective in actual use than the user's needs. For example, when used as a support mechanism for stage lighting, uneven swing speeds negatively impact the stage effect and reduce the viewer's visual experience. Similarly, when used as a clamping device for a sprinkler truck's water outlet, uneven swing speeds result in uneven water coverage, leading to unsatisfactory road cleaning and roadside plant cultivation. Using high-power motors also increases energy consumption, and the overall structure is complex with minimal benefits. Utility Model Content

[0007] A driving member is disposed in the inner cavity, and the driving member is used to drive the second end of the transmission rod to swing up and down around the first end;

[0008] An elastic buffer is disposed in the inner cavity and abuts against the second end at the top, and is connected to the bracket at the bottom;

[0009] A cantilever is provided on the outside of the bracket. The cantilever is connected to the rotating shaft and is fixed relative to the rotating shaft. The cantilever and the transmission rod can rotate simultaneously around the axis of the rotating shaft.

[0010] According to some embodiments of the present invention, a support plate is also included, which is disposed in the inner cavity and fixedly connected to the bracket, and the lower end of the elastic buffer is connected to the support plate.

[0011] According to some embodiments of the present invention, a guide rod is also included, which is vertically disposed on the support plate. The transmission rod is provided with a clearance hole for avoiding the guide rod, and the guide rod is used to guide the elastic buffer.

[0039] Reference Figures 1 to 4 According to the present invention, a vertical swing arm system includes: a bracket 100 having an inner cavity; a transmission rod 200 disposed in the inner cavity, the first end 201 of the transmission rod 200 being connected to and fixed relative to the rotating shaft 140, the middle part of the rotating shaft 140 being hinged to the side wall of the bracket 100; a driving member 300 disposed in the inner cavity, the driving member 300 being used to drive the second end 202 of the transmission rod 200 to swing up and down around the first end 201; an elastic buffer member 400 disposed in the inner cavity and abutting the second end 202 at its upper end, the lower end of which is connected to the bracket 100; and a cantilever 500 disposed on the outside of the bracket 100, the cantilever 500 being connected to and fixed relative to the rotating shaft 140. The cantilever 500 and the transmission rod 200 can rotate simultaneously around the axis of the rotating shaft 140. That is, when a load is suspended in the suspended section of the cantilever 500, the driving member 300 drives the second end 202 of the transmission rod 200 to swing up and down around the first end 201. This can be done by directly driving the second end 202 to move up and down, or by driving the first end 201 to rotate directly, thereby driving the rotating shaft 140 to rotate. The rotating shaft 140 then drives the cantilever 500 to rotate, thereby causing the suspended section of the cantilever 500 to swing. The elastic buffer 400 supports the second end of the transmission rod 200, so that when carrying the same weight of load, the output power required by the driving member 300 can be reduced.

[0040] The application of the above-mentioned vertical swing arm system has at least the following beneficial effects: the second end 202 of the transmission rod 200 is driven by the drive member 300 to swing around the first end 201. Since the rotating shaft 140, the transmission rod 200, and the cantilever 500 are all relatively fixed, the motion of the transmission rod 200 is transmitted to the rotating shaft 140 and then to the cantilever 500, thereby causing the suspended section of the cantilever 500 to swing up and down. At the same time, the elastic buffer member 400 provides support and buffer for the second end 202 of the transmission rod 200. When the load on the cantilever 500 is heavy, the elastic buffer member 400 can reduce the load received by the transmission rod 200 and reduce the reaction force on the drive member 300. This allows the swing arm system to bear loads that previously required a high-power drive member 300 when using a low-power drive member 300.

[0041] According to some embodiments of this utility model, it also includes a support plate 110, which is disposed in the inner cavity and fixedly connected to the bracket 100. The lower end of the elastic buffer 400 is connected to the support plate 110. In embodiments with multiple cantilever 500, the support plate 110 is provided in multiple pieces. The lower end of the elastic buffer 400 at the lowest end is directly connected to the bottom end of the bracket. A guide rod 120 is provided on each support plate 110. The guide rod 120 is vertically disposed on the support plate 110. The transmission rod 200 is provided with a clearance hole 210 for avoiding the guide rod 120. The guide rod 120 is used to guide the elastic buffer 400. The elastic buffer 400 is a compression spring. The guide rod 120 passes through the compression spring. While guiding the compression spring, the guide rod 120 can prevent the compression spring from disengaging from the second end 202 of the transmission rod 200, so that the compression spring can always maintain the supporting force on the transmission rod 200.

[0042] According to some embodiments of this utility model, the cantilever 500 is provided with at least two rods, and the transmission rod 200 and the cantilever 500 correspond one-to-one.

[0043] According to some embodiments of this utility model, it also includes a synchronizing link 130, which is vertically disposed in the inner cavity. The second end 202 of the transmission rod 200 is hinged to the synchronizing link 130 on the side away from the cantilever 500. In some embodiments, one of the transmission rods 200 can be powered by a single driving member 300. Under the action of the synchronizing link 130, multiple cantilever 500s can swing up and down simultaneously. Alternatively, multiple driving members 300 can be used to output power synchronously.

[0044] According to some embodiments of this utility model, the transmission rod 200 and the rotating shaft 140, as well as the cantilever 500 and the rotating shaft 140, are connected by a key, which achieves relative fixation. The key connection facilitates the installation and disassembly of the rotating shaft 140 with the transmission rod 200 and the cantilever 500.

[0045] According to some embodiments of the present invention, a protective cover 600 is provided on the side of the first end 201 of the transmission rod 200 away from the cantilever 500. The protective cover 600 is used to cover the protruding rotating shaft 140 to prevent dust from entering the rotating shaft 140 and affecting the smoothness of the rotation of the rotating shaft 140. At the same time, it can also prevent the rotating shaft 140 from being scratched and damaged.

[0046] According to some embodiments of the present invention, the driving component 300 is configured as a cylinder, which is located on the side wall of the bracket 100, and the output end of the cylinder is hinged to the second end 202 of the transmission rod 200.

[0047] According to some embodiments of the present invention, the driving component 300 is a motor, which is located on the side wall of the bracket 100 and is used to drive the rotating shaft 140 to rotate.

[0048] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0049] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as they achieve the technical effects of the present invention by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of this disclosure, without departing from the principles and purpose of the present invention, should be included within the scope of protection of this disclosure and should be considered to fall within the protection scope of the present invention.
