DETAILED DESCRIPTION

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-2 As shown, the utility model provides an outdoor automatic power supply arm waterproof protection device, including a base 1 for support and connection, and a plurality of conductive brushes 2 are installed on the base 1 at equal intervals. The conductive brush 2 is the core component of the power supply arm for power transmission, and therefore mainly provides waterproof protection for it.

[0020] Two symmetrical protective covers 3 are mounted on the exterior of the conductive brush 2. These covers are made of waterproof material, providing excellent sealing properties. These are shell-like components with uniform wall thickness. Specifically, they are sheet metal parts manufactured through a stamping and bending process, resulting in excellent corrosion resistance, light weight, and high strength and rigidity. The protective covers 3 on the left and right ends of the base 1 are symmetrical, allowing them to open and close synchronously, rotating at the same angle.

[0021] An opening and closing assembly 4 is installed at one end of the protective cover 3 for driving the two protective covers 3 to realize opening and closing actions to adapt to changes in the working state of the power supply arm.

[0022] The opening and closing assembly 4 includes a connecting rod 41 , a lifting rod 42 , an elastic member 43 and a first support 44 .

[0023] The connecting rod 41 is a long strip-shaped component with a rounded rectangular cross section. Through holes for hinge connection are provided at both ends of the connecting rod 41. One end of the connecting rod 41 is hinged to the protective cover 3, and the other end is hinged to the lifting rod 42.

[0024] The lifting rod 42 is a cylindrical straight rod, which is slidably mounted on a first support 44. Specifically, the lifting rod 42 slides vertically up and down on the first support 44. Furthermore, a slide 48 for supporting the sliding is mounted on the first support 44. The slide 48 is T-shaped, and the lifting rod 42 is also slidably connected to the slide 48. The slide 48 is fixedly mounted on the top of the first support 44. The slide 48 has a long hole that cooperates with the lifting rod 42, which increases the support surface for the sliding of the lifting rod 42 and further improves the stability of the lifting and sliding.

[0025] An elastic member 43 is mounted on the exterior of the lifting rod 42, with its upper and lower ends abutting one end of the lifting rod 42 and the first support 44, respectively. This elastic member 43 is primarily used to drive the protective cover 3 to automatically close when the conductive brush 2 is not powered, thereby protecting the conductive brush 2 from environmental influences. Specifically, this elastic member 43 is a compression spring, primarily designed to withstand axial forces. It effectively absorbs and releases energy when subjected to force and exhibits high elasticity.

[0026] A connecting plate 45 is fixedly mounted on the lifting rod 42. The connecting plate 45 is in the shape of a rectangular thin plate, and the connecting rods 41 are hinged at both ends in the length direction. The hinge positions of the left and right connecting rods 41 on the connecting plate 45 are symmetrical to each other. In this way, when the lifting rod 42 slides up and down, it can drive the two connecting rods 41 to move synchronously.

[0027] A contact piece 46 is fixedly mounted on the top of the lifting rod 42. This contact piece 46 is a thin, circular piece and is used to increase the contact area between the lifting rod 42 and the external electrical device. When the external electrical device draws power, it first contacts the contact piece 46. Furthermore, a crash pad is mounted on the contact piece 46. The crash pad absorbs and disperses impact force, effectively reducing or avoiding damage to objects caused by direct collisions, and can effectively reduce vibration and noise. In this embodiment, the crash pad is used to mitigate the impact between the external electrical device and the contact piece 46, preventing damage to the contact piece 46 or the external electrical device caused by the impact.

[0028] Furthermore, a baffle 47 is slidably mounted on the lifting rod 42 and disposed between the connecting plate 45 and the elastic member 43. The baffle 47 is annular, with its bottom surface abutting against the elastic member 43, thereby increasing the contact area with the elastic member 43. The top of the baffle 47 is held against the connecting plate 45, so that the baffle 47 can only slide in response to the compression of the elastic member 43. The bottom of the elastic member 43, in turn, abuts against the top of the slide 48.

[0029] A second support 5 is mounted on the end of the base 1 away from the first support 44, and both ends of the protective cover 3 are rotatably connected to the first support 44 and the second support 5. The second support 5 is mainly used to connect the protective cover 3 and is also a sheet metal part.

[0030] The working process of the utility model outdoor automatic power supply arm waterproof protection device is as follows:

[0031] When an external electrical device approaches, it first contacts the contact piece 46 to complete positioning. Then, the external electrical device maintains contact with the contact piece 46 and moves downward. The blocking piece 47 is subjected to the downward movement force of the connecting plate 45, which in turn compresses the elastic member 43. As the connecting plate 45 descends, it drives the left and right connecting rods 41 hinged on it to move, so that the connecting rods 41 drive the protective cover 3 to rotate a certain angle, thereby opening it, and finally making the conductive brush 2 contact with the external electrical device, completing the power collection process;

[0032] When the external electrical device leaves, it rises first, and the lifting rod 42 drives the baffle 47 under the action of the elastic member 43, thereby causing the lifting rod 42 to rise. The rising of the lifting rod 42 causes the connecting plate 45 to rise, thereby causing the connecting rod 41 hinged on the connecting plate 45 to move, and the connecting rod 41 drives the protective cover 3 to close, thereby protecting the conductive brush 2 from being affected by the external environment when no power is required.

[0033] In summary, the outdoor automatic power supply arm waterproof protection device provided by the utility model has the advantages of automatic opening and closing, good waterproof performance, stable and reliable structure and easy maintenance, and is suitable for power supply guarantee work in various harsh environments.

[0034] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
