DETAILED DESCRIPTION

[0020] Embodiments of the present invention: Figures 1 to 8 As shown, a portable hot and cold cup holder is used with a water cup with a concave bottom, including a frame 1, and a support plate assembly 2 is connected to both sides of the frame 1. The support plate assembly 2 includes a top plate 20 and a bottom plate 21 connected to each other. The top plate 20 has a convex portion 23 that matches the bottom of the water cup. A cooling plate is installed on the back of the convex portion 23 of the support plate assembly 2 on one side, and an electric heating element is installed on the back of the convex portion 23 of the support plate assembly 2 on the other side. A control device 18 and a power supply 19 are installed on the frame 1. The electric heating element, the cooling plate, and the power supply 19 are connected to the control device 18 through a circuit. The support plate assemblies 2 on both sides of the frame 1 are placed in the water by turning downward relative to the frame 1. When in a flat state, the water cup is placed on the support plate assembly 2, and the convex portion 23 fits with the bottom of the water cup. The control device controls the operation of the electric heating element and the refrigeration plate respectively, and the water cup placed on the corresponding support plate assembly 2 is heated and cooled by heat conduction. The convex portion 23 fits with the concave structure at the bottom of the water cup. On the one hand, it limits the water cup, making it difficult for the water cup to tip over. On the other hand, it reduces contact convection with air and has better heat conduction efficiency. When not in use, the support plate assembly 2 is flipped up to a storage and folded state, which is convenient to carry and saves storage space. The power supply 19 is a battery, and a connected charging interface 22 is provided on the side wall of the frame 1.

[0021] As a preferred embodiment, the frame 1 is connected with an arm guard assembly 3, which can be rotated relative to the frame 1 to be in an expanded state or a folded state. When the arm guard assembly 3 is in the expanded state, it cooperates with the frame 1 to protect the water cup placed on the pallet assembly 2, further preventing the water cup from tipping over. When not in use, it can be flipped to a folded state, which is convenient to carry and saves storage space.

[0022] As a preferred embodiment, the pallet assembly 2 has a fan-shaped gear portion 4, one end of the arm guard assembly 3 is connected to the frame 1 through a gear shaft 5, and a transmission gear 6 is installed on the frame 1 which is respectively engaged with the fan-shaped gear portion 4 and the gear shaft 5. The pallet assembly 2 and the arm guard assembly 3 are opened or folded by synchronously rotating through the fan-shaped gear portion 4, the gear shaft 5 and the transmission gear 6. Only one of the pallet assembly 2 or the arm guard assembly 3 needs to be flipped over to open or fold, and the other one can be synchronized and coordinated for easy operation.

[0023] As a preferred embodiment, a matching limiting mechanism is provided between the frame 1 and the pallet assembly 2, and the limiting mechanism includes an arc groove 24 provided on the frame 1, and a positioning column 7 provided on the pallet assembly 2 and slidingly matched with the arc groove 24. When the pallet assembly 2 rotates relative to the frame 1, the positioning column 7 slides in the arc groove 24, and the two ends of the arc groove 24 cooperate with the positioning column 7 to resist, and the arc groove 24 limits the rotation stroke. When the pallet assembly 2 rotates relative to the frame 1, the positioning column 7 slides in the arc groove 24. When the pallet assembly 2 is rotated to the open state, the positioning column 7 is located at one end of the arc groove 24, and is located at the other end of the arc groove 24 when it is in the stored and folded state, so that the pallet assembly 2 can be maintained in a horizontal open state or folded state, so that the water cup can be placed on the cup holder for carrying.

[0024] As a preferred embodiment, the arm guard assembly 3 is provided with a torsion spring 25 for resetting through the adapter end of the gear shaft 5, and the other end has a adapter part 8. The frame 1 is provided with a mounting opening 9 for the adapter part 8 to enter and realize rotational cooperation. The mounting opening 9 has a flange, and the adapter part 8 has a buckle 10 that cooperates with the flange. The adapter part 8 enters the mounting opening 9 and the buckle 10 is engaged with the flange to limit the adapter part 8 and can rotate in the mounting opening 9. A button 11 is slidably connected to the other side of the mounting opening 9, and a spring 12 is installed in the mounting opening 9 to act on the button 11 to move it outward. A limiting cavity is provided in the adapter part 8 of the present application, and the spring 12 is placed in the limiting cavity and is engaged with the button 11. The button 11 is connected to the mounting opening 9, and a matching resisting structure is provided between the button 11 and the mounting opening 9. When the spring 12 pushes the button 11 to move outward, the resisting structure resists and keeps the button 11 in a ready-to-press state, preventing the button 11 from separating from the mounting opening 9. The cross-sections of the button 11 and the mounting opening 9 are non-circular, and the button 11 can only move inward and outward relative to the mounting opening 9 and will not rotate relatively. The adapter 8 has a resisting portion 12, and the button 11 is provided with a matching resisting portion 2 14 with a guide surface 13 at the top. The two ends of the guide surface 13 of the resisting portion 2 14 are respectively a low end and a high end. When the arm guard assembly 3 is in the folded position, the button 11 is in a ready-to-press state, and the adapter 8 has a non-circular cross-section. The button 11 can only move inward and outward relative to the mounting opening 9 and will not rotate relatively. The adapter 8 has a resisting portion 12, and the button 11 is provided with a matching resisting portion 2 14 with a guide surface 13 at the top. The two ends of the guide surface 13 of the resisting portion 2 14 are respectively a low end and a high end. When the arm guard assembly 3 is in the folded position, the button 11 is in a ready-to-press state. The blocking portion 12 of the connecting portion 8 is close to the low end of the blocking portion 2 14. When the arm guard assembly 3 is rotated from the folded position to the open position, the torsion spring 25 is twisted to generate a force to reset the arm guard assembly 3. The blocking portion 12 is pressed down and contacted with the guide surface 13 of the blocking portion 2 14, and the button 11 is pulled inward. At this time, the spring 12 is gradually compressed. When the arm guard assembly 3 is rotated to the open position, the blocking portion 12 is separated from the guide surface 13 to release the blocking. The button 11 moves outward to the waiting state under the action of the spring 12. At this time, the blocking portion 12 is blocked with the high end of the blocking portion 2 14 to prevent the adapter 8 from reversing, thereby making the arm guard The component 3 remains in the open position, and the support plate component 2 is also maintained in the open position due to the synchronous transmission with the arm guard component 3. Pressing the button 11 causes the button 11 to move inward, and the blocking portion 12 and the blocking portion 2 14 are released. The arm guard component 3 is reversed and reset to the folded position under the action of the torsion spring 25. The blocking portion 12 of the adapter portion 8 is close to the low end of the blocking portion 2 14. The button 11 moves outward and resets to the ready-to-press state under the action of the spring 12. The support plate component 2 is synchronously transmitted to the folded position with the arm guard component 3. The conversion from the open state to the folded position is achieved by pressing the button 11, which is convenient for operation.

[0025] As a preferred embodiment, a pressure plate 15 is connected to the frame 1, and a torsion spring 16 is provided at the connection between the pressure plate 15 and the frame 1. The pressure plate 15 is kept in a state of pressing down the water cup placed on the support plate assembly 2 under the force of the torsion spring 16. When the water cup is placed on the support plate assembly, the pressure plate 15 rotates and presses the water cup under the force of the torsion spring 16, so as to better fix the water cup and prevent it from being overturned. When the cup holder is moving, the water cup will not move up and down to affect heating or cooling.

[0026] As a preferred embodiment, a buckle portion 17 is provided on one side of the frame 1, and the buckle portion 17 is fixed to the frame 1 by other buckling devices, so as to facilitate the fixed placement of the cup holder.
