Description

Technical Field

[0001] The invention relates to the field of vehicle-mounted cup holders, in particular to a vehicle-mounted lifting cup holder. Background Art

[0002] The center armrest cup holder is a design in the vehicle. As the name suggests, it is placed on the center armrest and its main function is to place cups. It is one of the basic functions configured in many models. Although the center armrest cup holder is a simple design, it brings great convenience to our lives. There is no need to hold the cup with the left hand and shift gears with the right hand, making the driving or riding experience smoother. The main function of the car cup holder is to fix and support beverage containers to prevent them from shaking or tipping over during driving, thereby keeping the interior environment of the car clean and safe. Car cup holders are widely used in various types of vehicles, including family sedans, SUVs, MPVs and RVs, etc. They not only provide convenience for drivers, but also increase the flexibility and utilization efficiency of storage space in the car.

[0003] When placing a cup in a traditional car cup holder, if the cup is open when the vehicle accelerates or stops, the water in the cup will spill out onto the central armrest due to inertia, soaking the vehicle or even penetrating into the interior of the vehicle, affecting the internal circuit. In addition, the vehicle may shake during operation, and the existing cup holder will cause the cup to shake synchronously due to the shaking, causing the water in it to spill out, making the placement of the cup unstable.

The water can only be splashed into the slide tube to avoid interference with the vehicle. The electric heating plate can dry the spilled water through the point-type water immersion sensor detection. Moreover, when the vehicle is bumpy, when the vehicle bumps left and right, the cup tube delays the left and right shaking amplitude of the cup tube under the rotation action of the inner ring and the second connecting shaft. Similarly, when the vehicle bumps back and forth, the cup tube delays the front and rear shaking amplitude of the cup tube under the rotation action of the bottom plate and the first connecting shaft, so that the water cup in the cup tube can be stably placed.

Furthermore, when the vehicle bumps, the water cup is stably placed and the spilled water can be dried to avoid interference with the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0021] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a vehicle-mounted lifting cup holder.

[0022] like Figure 1-9 As shown, a vehicle-mounted lifting cup holder includes: A placement hole is set at the central armrest, and a cup tube 1 is set in the placement hole. A slide tube 2 is slidably connected in the cup tube 1. It should be noted that the inner bottom of the slide tube 2 is a concave arc surface, and the bottom of the coaster 3 is a convex arc surface. The slide tube 2 matches the coaster 3, and the coaster 3 is placed in the slide tube 2. It should be noted that an electric heating plate 38 is embedded in the coaster 3, and a point-type water immersion sensor is installed at the bottom of the coaster 3. The point-type water immersion sensor is electrically connected to the electric heating plate 38. It should be noted that the placement hole and the cup tube 1 are connected through a corrugated cushion 39.

[0023] Through the above technical features, when the water in the cup is sprinkled into the slide 2, the point-type water immersion sensor detects the presence of water. At this time, the slide 2 can be dried by heating through the electric heating plate 38.

[0024] In order to prevent the water in the water cup from being splashed when the vehicle accelerates and decelerates, a tilting mechanism 4 is provided for tilting the water cup. The tilting mechanism 4 includes two fixed blocks 5 that slide through the cup barrel 1. It should be noted that one end of the fixed block 5 located in the cup barrel 1 is arranged in an arc shape. The fixed block 5 is made of soft rubber material. A fixed sleeve 6 is slidably sleeved outside the fixed block 5. The fixed sleeve 6 is fixedly connected to the outer wall of the cup barrel 1. The inner bottom of the fixed sleeve 6 is fixedly connected to the fixed block 5 by a spring 7. Two through holes 8 are penetrated on the cup barrel 1. The two through holes 8 are actively A first rotating shaft 9 and a second rotating shaft 10 are connected, and the first rotating shaft 9 and the second rotating shaft 10 located in the two through holes 8 are connected through a first transmission mechanism 11. Specifically, the first transmission mechanism 11 includes a first pulley 30 and a second pulley 31. The first pulley 30 is coaxially fixedly connected to the first rotating shaft 9, and the second rotating shaft 10 is coaxially fixedly connected to the second pulley 31. The first pulley 30 and the second pulley 31 are connected through a synchronous belt transmission. A slot 12 is provided on the fixed block 5, and the upper ends of the two first rotating shafts 9 are rotated to penetrate the cup tube 1 and extend to be set in the slot 12.

[0025] In the present invention, the upper end of the first rotating shaft 9 is coaxially fixedly connected with a gear 13, the slot 12 is provided with a tooth groove meshing with the gear 13, the slide cylinder 2 is provided with a sliding hole 14, the sliding hole 14 is slidably connected with a limit ring 15, the limit ring 15 is slidably connected with a push cylinder 16, the push cylinder 16 is connected to the second rotating shaft 10 through a second transmission mechanism 17, it is worth mentioning that the second transmission mechanism 17 includes a frame 32 arranged in the through hole 8, the frame 32 is fixedly connected with the limit ring 15, and the second rotating shaft 10 passes through the frame 3 2, a threaded push rod 33 is arranged in the frame 32, and the threaded push rod 33 is connected to the second rotating shaft 10 through a bevel gear set 34. One end of the threaded push rod 33 rotates through the frame 32 and is threadedly connected to the push cylinder 16. It should be noted that the bevel gear set 34 includes a first bevel gear 35 and a second bevel gear 36 that mesh with each other. A sliding sleeve 37 is slidingly sleeved outside the second rotating shaft 10. The first bevel gear 35 is coaxially fixedly connected to the sliding sleeve 37, and the second bevel gear 36 is coaxially fixedly connected to the threaded push rod 33.

[0026] Through the above technical features, when the vehicle accelerates or decelerates, the water cup will squeeze the fixed block 5 due to its own inertia, and the fixed block 5 moves. During the movement, the fixed block 5 drives the gear 13 to rotate, the gear 13 drives the first rotating shaft 9 to rotate, the first rotating shaft 9 drives the second rotating shaft 10 to rotate, the second rotating shaft 10 drives the threaded push rod 33 to rotate through the sliding sleeve 37, the threaded push rod 33 drives the push cylinder 16 to move, the push cylinder 16 pushes the coaster 3 to deviate at the bottom of the sliding cylinder 2, the coaster 3 drives the lower side of the water cup to deviate, so that the deflection direction of the lower side of the water cup is the same as the inertia direction of water, so that one side of the mouth of the water cup can be raised to prevent water from spilling out of the water cup.

[0027] After the vehicle is started, in order to prevent water from the cup from splashing onto the central armrest, a lifting mechanism 18 is provided to lift the slide 2. The lifting mechanism 18 includes a bidirectional threaded rod 19 rotatably connected to the inner wall of the cup barrel 1. The bidirectional threaded rod 19 is sleeved with two threaded blocks 20 on its outer thread. Furthermore, the two threaded blocks 20 are provided with threaded holes matching the bidirectional threaded rod 19. The threads in the two threaded holes have opposite rotation directions. The two threaded blocks 20 are both slidably connected to the inner bottom of the cup barrel 1. The upper ends of the two threaded blocks 20 are rotatably connected to a deflector plate 21. The upper ends of the two deflector plates 21 are both rotatably connected to the inner bottom of the slide 2. A motor 22 is fixedly mounted on the inner wall of the cup barrel 1. The drive shaft of the motor 22 is coaxially fixedly connected to the bidirectional threaded rod 19.

[0028] Through the above technical features, when the vehicle starts, the motor 22 drives the bidirectional threaded rod 19 to rotate, the bidirectional threaded rod 19 drives the two threaded blocks 20 to move relative to each other, the two threaded blocks 20 drive the slide 2 to descend through the two deflection plates 21, and the slide 2 drives the water cup to descend, so that the water cup can be completely placed inside the cup tube 1, avoiding the water in the water cup from being splashed onto the central armrest due to the severe shaking of the vehicle.

[0029] When the vehicle bumps, the water cup will also bump. In order to keep the water cup stably placed during the driving of the vehicle, a stabilizing mechanism 23 is set to maintain the stability of the cup tube 1. The stabilizing mechanism 23 includes a bottom plate 24. The cup tube 1 is mounted on the bottom plate 24. An inner ring 25 and an outer ring 26 are sequentially sleeved on the outside of the bottom plate 24. The front and rear sides of the inner wall of the inner ring 25 are rotatably connected to the bottom plate 24 through a first connecting shaft 27, and the left and right sides of the outer wall of the inner ring 25 are rotatably connected to the outer ring 26 through a second connecting shaft 28. Two mounting plates 29 are installed on the inner side of the central armrest, and the outer ring 26 is fixedly installed to the mounting plate 29.

[0030] Through the above technical features, when the vehicle bumps left and right, the cup tube 1 is slowed down from shaking left and right due to the rotation of the inner ring 25 and the second connecting shaft 28. Similarly, when the vehicle bumps forward and backward, the cup tube 1 is slowed down from shaking forward and backward due to the rotation of the bottom plate 24 and the first connecting shaft 27, so that the water cup in the cup tube can be stably placed.

[0031] Working principle: 1) When the vehicle starts, the motor 22 drives the bidirectional threaded rod 19 to rotate, and the bidirectional threaded rod 19 drives the two threaded blocks 20 to move relative to each other. The two threaded blocks 20 drive the slide 2 to descend through the two deflection plates 21, and the slide 2 drives the water cup to descend, so that the water cup can be completely placed inside the cup tube 1, avoiding the water in the water cup from being splashed onto the central armrest due to the severe bumps of the vehicle.

[0032] 2) When the vehicle bumps, the cup tube 1 slows down the left and right shaking amplitude of the cup tube 1 due to the rotation of the inner ring 25 and the second connecting shaft 28. Similarly, when the vehicle bumps forward and backward, the cup tube 1 slows down the forward and backward shaking amplitude of the cup tube 1 due to the rotation of the bottom plate 24 and the first connecting shaft 27, so that the water cup in the cup tube can be stably placed.

[0033] 3) When the vehicle accelerates and decelerates, the water cup will squeeze the fixed block 5 due to its own inertia, and the fixed block 5 moves. During the movement, the fixed block 5 drives the gear 13 to rotate, the gear 13 drives the first rotating shaft 9 to rotate, the first rotating shaft 9 drives the second rotating shaft 10 to rotate, the second rotating shaft 10 drives the threaded push rod 33 to rotate through the sliding sleeve 37, the threaded push rod 33 drives the push cylinder 16 to move, the push cylinder 16 pushes the coaster 3 to deviate at the bottom of the sliding cylinder 2, the coaster 3 drives the lower side of the water cup to deviate, so that the deflection direction of the lower side of the water cup is the same as the inertia direction of water, so that one side of the mouth of the water cup can be raised to prevent water from spilling out of the water cup.

[0034] 4) When the water in the cup is sprinkled into the slide tube 2, the point-type water immersion sensor detects the presence of water. At this time, the slide tube 2 can be dried by heating through the electric heating plate 38.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
