Description

Technical Field

[0001] The utility model relates to the technical field of waterproofing of wireless charging control devices, and particularly relates to a waterproof wireless charging control device. Background Art

[0002] Wireless charging technology originates from wireless power transmission technology. Its principle is that energy is transmitted between a charger and an electrical device through a magnetic field. It can be divided into two types: low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction; high-power wireless charging often uses resonance, and the power supply device transmits energy to the electrical device.

[0003] For example, a waterproof wireless charging device for an agricultural greenhouse controller sensor, with the publication number CN212033795U. For such a wireless charging device, the device mainly consists of a device housing, a charging board, and an infrared sensor. When using this device, first, attach the device to the wireless induction panel that needs to be charged, and then rotate the upper and lower sets of fitting rods and push the left end face of the fitting rod to the left so that the fitting rubber strip on the left end face of the fitting rod can adhere to the panel, thus fixing the device. At this time, the waterproof rubber strip installed on the side end face of the device housing adheres to the wireless charging panel to achieve waterproofing. Then, take out the connecting rod from the side surface of the device housing to disengage the limit plate, and through the elastic force of the spring, the two springs push the support bottom plate to move leftward. In this way, by using the movable connection between the support bottom plate and the inner surface of the device housing, the charging board is made to adhere to the panel at the left opening of the device housing.

[0004] However, when the limit plate is installed in the housing, there is a gap between the charging board and the left opening of the device housing, and it does not contact the waterproof rubber strip, that is, sealing and waterproofing cannot be achieved at this time.

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Such as Figures 1-4As shown, a waterproof wireless charging control device comprises a housing 1 and a charging plate 13 in the housing 1. The inner wall of the housing 1 is rotatably connected to two symmetrically arranged opening and closing plates 7 near the housing opening. A plurality of spring hinges 19 are installed between the opening and closing plates 7 and the inner wall of the housing 1. The core shaft of the spring hinge 19 is fixed to a hinge on one side of the opening and closing plates 7. When the two opening and closing plates 7 are kept in a closed state under the elastic force of the spring hinge 19, a sealing gasket is installed around the opening and closing plates 7 to achieve sealing, that is, to ensure that the two opening and closing plates 7 are closed. The charging plate 13 can be isolated from the housing opening of the housing 1, that is, the charging plate 13 is waterproof when not in use. In addition, when the charging plate 13 needs to be used, the core shaft end faces of the plurality of spring hinges 19 on the same opening and closing plate 7 extend outward to form a The whole is provided with one end of the core shaft of the spring hinge 19 extending toward the side wall of the shell 1, and a main traction rope 8 is provided through the positions near the extended ends of the spring hinge 19 on both sides of the shell 1. One end of the main traction rope 8 is spherical, and the other end again passes through the outer wall of one side of the shell 1 and extends to be fixed at the extended part of the spring hinge 19 adjacent to it. An auxiliary traction rope 17 is connected between the extended end of the spring hinge 19 on the other opening and closing plate 7 and the main traction rope 8. By pulling one end of the spherical part of the main traction rope 8, the other end of the main traction rope 8 can overcome the elastic force of the spring hinge 19, so that the core shaft of the spring hinge 19 drives the hinge on one side fixed thereto to rotate, thereby realizing the connected opening and closing plate 7 to rotate and open, and the auxiliary traction rope 17 can similarly pull the opening and closing plate 7 on the other side to rotate and open.

[0024] In addition: screws 11 are inserted at both ends of the outer wall of the shell 1, and a suction cup 9 is fixedly installed at one end of the screw 11. A sprocket ring 12 threadedly connected to the screw 11 is rotatably connected to the outer wall of the shell 1, and a chain is meshed between the two sprocket rings 12. The two sprocket rings 12 can be rotated simultaneously by pulling the chain, and then the threaded screw 11 drives the suction cup 9 to move under the limiting effect of the shell 1, so that the suction cup 9 is firmly adsorbed on the surface of the equipment. In addition, the sprocket ring 12 in this scheme is threadedly connected to the screw 11 by processing a thread groove on the inner wall, and a sealing gasket is also provided at the shell opening of the shell 1 to ensure that the shell 1 is sealed and waterproof around the shell opening when the shell 1 is in the adsorbed state.

[0025] In addition: the inner wall of the shell 1 is located on the back of the charging plate 13 and is rotatably connected to two symmetrically arranged connecting shafts 15, and the two connecting shafts 15 are fixedly connected to the two connecting shafts 15. The two spur gears 14 are meshingly connected and the tooth surfaces of the spur gears 14 are fixedly connected to a push plate 16 for pushing the charging plate 13. A spring 18 is connected between the back corner of the charging plate 13 and the inner wall of the shell 1. By rotating one of the spur gears 14 to achieve the reverse rotation of the other spur gear 14, the two push plates 16 can push the charging plate 13 to overcome the pulling force of the spring 18 and move through the two opened opening and closing plates 7 to contact the device, thereby realizing wireless charging.

[0026] In addition, one end of one connecting shaft 15 extends outward and is fixedly connected to a driven bevel gear 2. A worm gear 4 is rotatably connected to the outer wall of the housing 1 near the driven bevel gear 2. A driving bevel gear 3 fixedly connected to the end face of the worm gear 4 and meshed with the driven bevel gear 2 is provided. A worm 10 meshed with the worm gear 4 is rotatably connected to the outer wall of the housing 1. A small gear 5 is fixedly connected to the end face of the worm 10, and a large gear 6 meshed with the small gear 5 is rotatably connected to the outer wall of the housing 1. By rotating the large gear 6, the small gear 5 drives the worm 10 to rotate rapidly, and then the meshed worm gear 4 drives the driving bevel gear 3 to rotate, so that the meshed driven bevel gear 2 drives the corresponding connecting shaft 15 to rotate, and one of the straight gears 14 can be rotated.

[0027] Working principle: When charging is required, one end of the spherical part of the main traction rope 8 is pulled, and with the assistance of the auxiliary traction rope 17, the two opening and closing plates 7 are rotated and opened. Then, the large gear 6 is rotated. Under the driving action of the meshing connection between the small gear 5, the worm 10 and the worm gear 4, one of the connecting shafts 15 drives the corresponding straight gear 14 to rotate. By rotating one of the straight gears 14, the other straight gear 14 rotates in the reverse direction, so that the two push plates 16 push the charging plate 13 to move through the two opened opening and closing plates 7 against the pulling force of the spring 18 and contact the device, realizing wireless charging.

[0028] The wiring diagram of the charging plate 13 in the present utility model belongs to the common knowledge in the art. Its working principle is a known technology, and its model is selected according to actual use. Therefore, the control method and wiring layout of the charging plate 13 will not be explained in detail.
