[0033] like Figure 1-Figure 5As shown, in this embodiment, the vehicle-mounted water cup heating device includes a water cup 1, a heating mechanism, and a return spring 13. The bottom of the water cup 1 is provided with a contact 2, and the heating mechanism includes a protective assembly and a drive assembly. The drive assembly includes a base 3, a button 4, and a chuck 5. The chuck 5 is rotatably mounted within the base 3, which defines a passage. The button 4 extends through a through-hole in the chuck 5 and slides within the passage. The through-hole in the chuck 5 defines a first slide groove. The button 4 is provided with a spiral guide bar 6, which slides within the first slide groove to enable the chuck 5 to rotate relative to the base 3. The protective component includes a guide seat 7, a contact seat 8 and multiple baffles 9. The guide seat 7 and the contact seat 8 are both arranged on the base 3. The guide seat 7 has an opening, and the contact seat 8 is located in the opening. Multiple baffles 9 are rotatably arranged on the guide seat 7 and surrounded by the button 4. The guide seat 7 is provided with a guide groove 10. The baffle 9 is provided with a first protrusion 11 and a second protrusion 12. The first protrusion 11 is slidably arranged in the guide groove 10, and the second protrusion 12 is connected to the chuck 5. Under the rotation action of the chuck 5, the multiple baffles 9 can slide along the extension direction of the guide groove 10 and open the opening so that the contact seat 8 can be electrically connected to the contact 2. The two ends of the reset spring 13 are respectively connected to the button 4 and the base 3.

[0034] The water cup 1 is configured as an electrically heated cup. The base 3 has a receiving cavity. The chuck 5 is disposed within the receiving cavity and is rotatably engaged with the base 3. The guide seat 7 is located above the chuck 5 and mounted on the base 3. The contact seat 8 is located within the receiving cavity and mounted on the guide seat 7. The contact seat 8 is electrically connected to the vehicle power supply. The guide seat 7 defines a guide groove 10 having an inclined arc-shaped structure. Multiple baffles 9 are slidably disposed within the guide seat 7. First protrusions 11 on the tops of the multiple baffles 9 slidably engage with the guide grooves 10 of the guide seat 7 to control the sliding trajectory of the baffles 9. Second protrusions 12 on the bottoms of the multiple baffles 9 pass through the guide seat 7 and are connected to the chuck 5 to control the movement of the baffles 9. The button 4 is located at the center of the multiple baffles 9 and is retractable relative to the opening of the guide seat 7. In the default state, the multiple baffles 9 abut the outer periphery of the button 4 to form a sealing structure. A through hole is provided at the center of the chuck 5, and a channel is provided at the corresponding position of the base 3. The button 4 is inserted into the through hole and slidably arranged in the channel. A spiral guide bar 6 is provided on the outside of the bottom of the button 4. The through hole of the chuck 5 is provided with a first slide groove. When the water cup 1 presses the button 4, the button 4 can slide downward in the channel, and the spiral guide bar 6 slides in the first slide groove to rotate the chuck 5. The chuck 5 drives multiple baffles 9 to slide along the guide groove 10 to spread outward, so that the opening of the guide seat 7 is opened, and the contact seat 8 is exposed and contacts with the contact 2 of the water cup 1 to be energized, thereby realizing power supply to the water cup 1. The water cup 1 can be heated, which is convenient for boiling water in the car. When the heating is completed, pick up the water cup 1 to disconnect, and the button 4 slides upward in the channel under the elastic action of the reset spring 13, and the spiral guide bar 6 slides in the first slide groove to make the chuck 5 rotate in the opposite direction. The chuck 5 drives the multiple baffles 9 to slide along the guide groove 10 to shrink inward, so that the opening of the guide seat 7 is closed, and the contact seat 8 is hidden under the multiple baffles 9, which has the effect of preventing accidental touch, and prevents liquid from dripping into the interior and causing a short circuit, with good safety.

[0035] Reference Figure 3-Figure 5The guide seat 7 includes a first guide plate 15 and a second guide plate 16. The first guide plate 15 and the second guide plate 16 are arranged in a lockable manner and have an accommodation space. Multiple baffles 9 are all located in the accommodation space. The first guide plate 15 is provided with a guide groove 10, and the first protrusion 11 is slidably arranged in the guide groove 10. The second guide plate 16 is provided with a connecting hole 17, and the second protrusion 12 is slidably inserted into the connecting hole 17. The chuck 5 is provided with a plurality of notches 14. The plurality of notches 14 are arranged at intervals along the circumference of the chuck 5. The second protrusions 12 of the multiple baffles 9 are respectively fixedly engaged with the notches 14. Part of the baffle 9 is slidably arranged in the accommodation space, and the other part is located at the opening position of the guide seat 7. The first protrusion 11 at the top of the baffle 9 slides with the guide groove 10 of the first guide plate 15. The second protrusion 12 at the bottom of the baffle 9 slides through the connecting hole 17 of the second guide plate 16 and is engaged with the corresponding notch 14 of the chuck 5. The rotation of chuck 5 causes second protrusion 12 to rotate within notch 14, simultaneously driving multiple baffles 9 to slide along the extension direction of guide slot 10, allowing baffles 9 to contract inward or expand outward, thereby closing or opening the opening of guide seat 7. When baffles 9 open the opening, contacts 2 at the bottom of cup 1 directly contact and electrically connect with contact seat 8, heating cup 1. When baffles 9 close the opening, contact seat 8 is concealed beneath them, preventing fingers from accidentally entering and causing electric shock.

[0036] Reference Figure 5 The button 4 is also provided with a vertical guide bar 18. A second chute is defined on the inner wall of the channel. The second chute extends along the axis of the button 4, and the vertical guide bar 18 slides in the second chute. The button 4 slides upward or downward within the channel in cooperation with the vertical guide bar 18 and the second chute. Simultaneously, the button 4, in cooperation with the spiral guide bar 6 and the first chute, rotates the chuck 5, driving the multiple baffles 9 to open or close the openings of the guide seat 7.

[0037] Continue to refer to Figure 5The button 4 includes a contact portion 19, a guide portion 20, and a limit portion 21. The contact portion 19 is arranged between the multiple baffles 9 and slides through the opening. When the multiple baffles 9 close the opening, the contact portion 19 can fit with the multiple baffles 9. The guide portion 20 is arranged through the through hole of the chuck 5 and slides in the channel. The limit portion 21 is arranged between the contact portion 19 and the guide portion 20. When the multiple baffles 9 open the opening, the limit portion 21 can abut against the chuck 5. The cross-section of the contact portion 19 is a triangular structure, corresponding to the number of baffles 9 being three. When the baffles 9 close the opening of the guide seat 7, the baffles 9 fit with the contact portion 19, that is, the three baffles 9 are respectively sealed and fitted to the outer peripheral surface of the contact portion 19, ensuring that there is no gap between the button 4 and the multiple baffles 9, preventing fingers from passing through the gaps and opening the baffles 9 through external force, further playing a protective role. There are multiple spiral guide bars 6 and vertical guide bars 18, spaced apart along the circumference of the guide portion 20. The vertical guide bars 18 slide in conjunction with the second chute, while the spiral guide bars 6 slide in conjunction with the first chute, allowing the guide portion 20 to slide within the channel while simultaneously rotating the chuck 5. Furthermore, the guide portion 20 slides downward until the stopper 21 abuts the chuck 5, at which point it stops sliding, ensuring that the button 4 slides within a certain range. This prevents water cups 1 of varying weights from sliding excessively downward upon contact with the button 4, preventing it from rebounding and thus affecting its usability.

[0038] Continue to refer to Figure 5 The heating mechanism further includes a rotating spring 22, which is disposed between the base 3 and the contact seat 8. The rotating spring 22 can increase the fault tolerance when the distance between the contact seat 8 and the contact 2 is too large. When the distance between the contact seat 8 and the contact 2 is too large, the contact seat 8 actively rotates under the action of the rotating spring 22 to dock the contact 2 of the water cup 1, ensuring accurate docking.

[0039] Continue to refer to Figure 5The heating mechanism also includes a first magnet 23 and a second magnet 24. The first magnet 23 is mounted on the contact holder 8, and the second magnet 24 is mounted on the bottom of the cup 1. The first magnet 23 and the second magnet 24 are magnetically connected. The contact holder 8 is provided with multiple spring contacts 27, which can extend and retract relative to the contact holder 8 and are electrically connected to the contact 2. When the cup 1 presses the button 4 downward, the baffle 9 opens, and the contact 2 contacts the multiple spring contacts 27 of the contact holder 8. Simultaneously, the first magnet 23 and the second magnet 24 magnetically secure the cup 1 relative to the heating mechanism, ensuring good contact between the contact 2 of the cup 1 and the contact holder 8. This prevents contact loss due to external forces, which could affect the heating effect of the cup 1. When the cup 1 is heated, the cup 1 is lifted, the button 4 is reset, and the multiple baffles 9 close the opening of the guide holder 7. Simultaneously, the spring contacts 27 of the contact holder 8 extend under their own elasticity, allowing for good contact with the contact 2 of the cup 1 the next time.

[0040] Reference Figure 1-Figure 2 The water cup 1 includes a cup body 25 and a heater 26. The heater 26 is located at the bottom of the cup body 25 and is electrically connected to the contact 2. When the contact 2 is electrically connected to the contact holder 8, the heater 26 heats the cup body 25. The cup body 25 has a double-layer hollow structure, providing a certain degree of insulation. A temperature sensor 28 and the heater 26 are located at the bottom of the cup body 25. The heater 26 is a 12V ceramic heater 26. The positive and negative terminals of the heater 26 and the temperature sensor 28 are electrically connected to the contact 2 via wires. A control circuit board is built into the cup body, which is electrically connected to the heater 26. When the contact 2 mates with the spring contact 27 of the contact holder 8, current is connected, and the heater 26 heats the liquid in the cup body 25. When the temperature sensor 28 detects that the liquid temperature in the cup body 25 reaches the set value, it sends a high signal to the control circuit board, which controls the heater 26 to turn off, stopping heating. The cup body 25 is lifted to disconnect.

[0041] The working principle of the car-mounted water cup heating device is as follows:

[0042] When cup 1 is placed into the heating mechanism, the contact portion 19 of button 4 is pressed from the bottom of cup 1. The vertical guide bar 18 slides in engagement with the second slide groove, and the guide portion 20 slides downward within the channel. Simultaneously, the spiral guide bar 6 slides in engagement with the first slide groove, causing chuck 5 to rotate. Chuck 5 then drives multiple baffles 9 to slide along the extension direction of guide groove 10, causing them to spread outward and open the opening of guide seat 7. The limiting portion 21 abuts chuck 5, causing chuck 5 to stop rotating. The multiple baffles 9 open to their maximum extent. Under the magnetic attraction of first magnet 23 and second magnet 24, cup 1 is fixed relative to the heating mechanism. Simultaneously, contact 2 of cup 1 contacts multiple spring contacts 27 of contact seat 8. Power is turned on, and cup 1 begins to heat. After the water cup 1 is heated, the water cup 1 is lifted up, and the button 4 slides upward in the channel under the elastic action of the return spring 13. The spiral guide bar 6 slides in the first slide groove to make the chuck 5 rotate in the opposite direction. The chuck 5 drives the multiple baffles 9 to slide along the guide groove 10 to shrink inward, so that the opening of the guide seat 7 is closed, and the contact seat 8 is hidden under the multiple baffles 9 to prevent accidental touch.
