[0022] This utility model proposes a tri-proof waterproof charging stand for mobile phones.

[0023] like Figures 1 to 2 As shown in one embodiment of this utility model, a rugged waterproof charging dock for mobile phones includes a charging dock body 1. The upper end of the charging dock body 1 is provided with a charging slot 2 for inserting a rugged mobile phone for charging. The charging dock body 1 has power receiving slots on opposite sides of the charging slot 2. Power receiving posts 3 are installed in the power receiving slots respectively. Each power receiving post 3 has a telescopic component connected to its end facing away from the opening of the power receiving slot, allowing the power receiving post 3 to extend and retract. A sealing component 16 is installed at the power receiving slot to block the charging slot 2. The charging dock body 1 has a first mounting groove on one side of the charging slot 2. The bottom of the first mounting slot is equipped with a first micro switch for controlling the power supply of the power terminal 3. The first mounting slot is embedded with a power button 6, which abuts against the first micro switch. The power button 6 has rounded corners. The charging base has a water channel 7 at the bottom of the charging slot 2 that connects to the outside of the charging base body 1. When the rugged phone is inserted into the charging slot 2, the sealing component 16 moves away from the power terminal, and the telescopic component extends the power terminal 3 to charge the rugged phone. When the rugged phone is pulled out of the charging slot 2, the telescopic component retracts the power terminal 3, and the sealing component 16 blocks the power terminal for waterproofing.

[0024] In this embodiment, by placing the positive and negative terminals 3 on both sides of the charging slot 2, the positive and negative poles of the charging base body 1 are separated, which can prevent short circuits caused by contact between the positive and negative terminals 3 and water to a certain extent. The telescopic component allows the terminals 3 to extend and retract, and the sealing component 16 can seal the charging slot in time when charging is not needed to prevent water from contacting the terminals 3, further increasing the waterproof performance of the charging base body 1. In addition, through the first micro switch and the power button 6, the circuit of the terminals 3 can be connected when a rugged phone is inserted into the charging slot 2 and disconnected when the rugged phone is removed, further increasing the waterproof performance and safety. The water flow channel 7 at the bottom of the charging slot 2 can drain the water in the charging slot 2 out of the charging base body 1 in time, preventing excessive water accumulation from flooding the terminals 3 on both sides of the charging slot 2 and causing a short circuit.

[0025] Specifically, the charging base body 1 is made of high-strength, water-resistant, and corrosion-resistant engineering plastics, such as reinforced polycarbonate (PC), which can be injection molded. On opposite sides of the charging slot 2, connection grooves are injection molded, and on one side of the charging slot 2, a first mounting groove is injection molded. A water flow channel 7 is integrally formed at the injection-molded bottom of the charging slot 2. The connection post 3 is made of a highly conductive and oxidation-resistant metal material, such as copper alloy, and is silver-plated on the surface to reduce contact resistance and improve conductivity. The telescopic component can be a miniature electric actuator, which controls the telescopic movement of the connection post 3. The sealing component 16 includes a sealing cover and a sealing rubber ring. The first microswitch is a small, sensitive microswitch whose triggering force and stroke should match the connection button 6, for example, a triggering force of 0.5-1N and a stroke of 1- 2mm; The power button 6 is made of a plastic material with certain strength and insulation properties, such as bakelite, and is injection molded. The power button 6 has rounded corners, making it hemispherical or arc-shaped, which serves as a guide. When the rugged phone is inserted, the rounded corners cause the power button 6 to retract into the first mounting groove, triggering the first micro switch. Preferably, such as Figure 2As shown, the telescopic assembly includes two L-shaped components 13. A U-shaped groove 12 is provided around the charging slot 2. The power connection slots are all connected to the upper ends of the U-shaped groove 12. The two L-shaped components 13 are respectively embedded on both sides of the U-shaped groove 12 and are positioned opposite each other. Power connection posts 3 are fixedly connected to the upper ends of the two L-shaped components 13. Each of the two L-shaped components 13 has a support post 14 at its lower end, which is fixedly connected to the bottom of the U-shaped groove 12, serving as a fulcrum for the two L-shaped components 13. An elastic member 15 is fixedly connected to the opposite side of the lower end of each of the two L-shaped components 13. The other end of the elastic member 15 is connected to the U-shaped groove 12. The bottom of the groove 12 abuts against the wall, and the elastic element 15 is located between the two supports. The elastic element 15 lifts up the L-shaped part 13, thereby causing the other end of the L-shaped part 13 to retract into the charging groove. The charging base body 1 has a groove at the bottom of the charging groove 2 that connects to the U-shaped groove 12. A pressing post 4 is movably inserted in the groove. The bottom of the pressing post 4 abuts against the side opposite to the lower end of the two L-shaped parts 13. When the rugged phone is inserted into the charging groove 2, the rugged phone presses the pressing post 4, thereby pressing down the bottom of the L-shaped part 13, causing the upper end of the L-shaped part 13 to drive the charging post 3 out of the charging groove to charge the rugged phone.

[0026] Preferably, such as Figure 2 As shown, a pressure plate 17 is fixedly connected to the bottom of the pressing column 4. The two ends of the bottom of the pressure plate 17 abut against the two L-shaped parts 13 respectively. The pressure plate 17 can better press the bottom of the two L-shaped parts 13 at the same time.

[0027] Furthermore, a flexible sealing ring is fitted on the upper end of the pressing column 4. One end of the flexible sealing ring is fixedly connected to the pressing column 4, and the other end is fixedly connected to the bottom of the charging slot 2. The flexible sealing ring can prevent water from entering the U-shaped groove 12 from the gap between the pressing column 4 and the charging base body 1.

[0028] Preferably, such as Figures 3 to 4 As shown, the sealing assembly 16 includes a sealing plate 19 and a drive motor 20. The charging base has a sliding groove on the side wall of the U-shaped groove 12. The sealing plate 19 is embedded in the sliding groove and slidably connected to the side wall of the U-shaped groove 12 so that the sealing plate 19 is inserted into the charging slot. A rack is provided on one side of the sealing plate 19. A gear is fixedly connected to the output end of the drive motor 20 so that the gear and the rack mesh with each other. The drive motor 20 is fixedly connected to the charging base body 1. By driving the drive motor 20, the extension and retraction movement of the sealing plate 19 can be controlled. When not charging, the sealing plate 19 is controlled to seal the charging slot and isolate the charging post 3 from the outside. When charging, the drive motor 20 is controlled to open the charging slot so that the charging post 3 can extend.

[0029] Preferably, such as Figure 4As shown, the charging base body 1 has a support cover at the sealing plate 19. The support cover is fixedly connected to the side wall of the U-shaped groove 12. The sealing plate 19 is inserted into the support cover and movably connected to the support cover. Multiple elastic extrusion members 21 are fixedly installed inside the support cover. The elastic extrusion members 21 abut against the sealing plate 19 to make the sealing plate 19 and the U-shaped groove 12 tightly abut against each other. The elastic extrusion members 21 can extrude the sealing plate 19 to increase the sealing effect of the sealing plate 19 and the charging groove. The elastic extrusion members 21 can be springs, leaf springs or plastic products with a certain elasticity, and there are no restrictions here.

[0030] Preferably, the elastic compression member 21 includes a fixed cylinder, a spring, and a ball bearing. The fixed cylinder is fixedly connected to the support cover, the spring is embedded in the fixed cylinder, and the ball bearing is embedded in the fixed cylinder and rotatably connected to the fixed cylinder. The end of the ball bearing away from the fixed cylinder abuts against the sealing plate 19. The compression of the ball bearing by the spring further compresses the sealing plate 19. The ball bearing can reduce the friction force between the sealing plate 19 and the sealing plate 19, so that the sealing plate 19 can move smoothly in extension and retraction, and avoid the situation where the elastic compression member 21 jams the sealing plate 19.

[0031] Preferably, such as Figure 4 As shown, the sealing plate 19 has an elastic sealing protrusion 22 on the side away from the support cover. The elastic sealing protrusion 22 is matched with the size of the electrical connection groove. The elastic sealing protrusion 22 has a smooth guide part. The elastic sealing protrusion 22 can further seal the electrical connection groove, while the smooth guide part can allow the sealing plate 19 to move smoothly and avoid jamming. The elastic sealing protrusion 22 can be a rubber ring or a protrusion made of other elastic materials.

[0032] Preferably, the charging base body 1 has a second mounting groove on one side of the charging slot 2. A proximity switch is installed at the bottom of the second mounting groove, and a spring is also installed inside the second mounting groove. The proximity switch is electrically connected to the drive motor 20. A press button 5 is embedded in the second mounting groove. The press button 5 abuts against the spring. An arc-shaped guide part is provided at the end of the press button 5 near the opening of the mounting groove. When a rugged phone is inserted, the press button 5 moves towards the bottom of the mounting groove under the action of the arc-shaped guide part, so that the press button 5 is close to the proximity switch. After the proximity switch detects the press button 5, it controls the drive motor 20 to drive the sealing plate 19 to move and open the charging slot. Similarly, when the rugged phone is pulled out of the charging slot 2, the press button 5 moves away from the proximity switch under the action of the spring, thereby controlling the drive motor 20 to drive the sealing plate 19 to block the charging slot.

[0033] Preferably, such as Figure 1As shown, the charging base body 1 has a power inlet 8 on one side, and an elastic sealing element 9 is provided around the power inlet 8. The charging base has fixing posts 10 on opposite sides of the power inlet 8 for fixing the connector of the power cable. The charging base body 1 has a triangular snap-fit ​​part 11 at one end. When the power cable of the external power cable is inserted, the triangular snap-fit ​​part 11 snaps and fixes the power cable connector. The connector of the power cable is tightly connected to the elastic sealing element 9, thereby achieving waterproofing of the power inlet 8.

[0034] Specifically, the working principle and usage process of this utility model are as follows: By setting the positive and negative terminals 3 on both sides of the charging slot 2, the positive and negative poles of the charging base body 1 are separated, which can prevent the positive and negative terminals 3 from coming into contact with water and causing a short circuit to a certain extent. The telescopic component can extend and retract the terminals 3, and the sealing component 16 can seal the charging slot in time when charging is not needed to prevent water from coming into contact with the terminals 3, further increasing the waterproof performance of the charging base body 1. In addition, through the first micro switch and the power button 6, the circuit of the terminals 3 can be connected when a rugged phone is inserted into the charging slot 2 and disconnected when the rugged phone is pulled out, further increasing the waterproof performance and safety. The water flow channel 7 at the bottom of the charging slot 2 can drain the water in the charging slot 2 out of the charging base body 1 in time, preventing too much water from flooding the terminals 3 on both sides of the charging slot 2 and causing a short circuit.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
