Description

Technical Field

[0001] The present invention relates to the technical field of electric skateboard luggage, and more particularly, to a combined electric skateboard luggage. Background Art

[0002] In the fast-paced world of modern travel, people often need to carry both luggage and a short-distance mobility device. Traditionally, these separate devices, such as suitcases and electric scooters, take up a lot of space when carried, making them difficult to place on public transportation and prone to collisions with other passengers. They are also extremely inconvenient when going up and down stairs or through narrow passages. Switching from walking to mobility requires first placing the suitcase and then using the scooter, a cumbersome and inefficient process.

[0003] Existing modes of transportation, such as skateboards, have limited braking capabilities and rely heavily on simple friction braking. This results in long braking distances in emergencies, posing safety risks. Furthermore, kinetic energy is converted into heat and dissipated during braking, lacking an energy recovery mechanism. Furthermore, when not in use, luggage requires roller cleaning to maintain cleanliness and extend its lifespan. Therefore, developing a combined electric skateboard suitcase that seamlessly integrates luggage with a skateboard, offering efficient braking, convenient operation, and effective roller cleaning and maintenance, is crucial to solving today's travel challenges.

DETAILED DESCRIPTION

[0032] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0033] Example 1: Please refer to Figure 1-12Structural schematic diagram, the present invention provides the following technical solutions: A combined electric skateboard suitcase, comprising a skateboard 1 and a suitcase 2, the skateboard 1 being provided with four lock holes 101, the bottom of the suitcase 2 being provided with four lock pins 3 respectively inserted into the four lock holes 101, and the bottom of the skateboard 1 being provided with four rollers 4, two rotating seats 5 being provided at the rear end of the bottom of the skateboard 1, the two rotating seats 5 being provided with a rotating shaft 6 for rotating together, two tires 7 being provided at both ends of the rotating shaft 6, and two sets of brake assemblies being provided on the skateboard 1.

[0034] Specifically, when the suitcase 2 needs to be placed on the slide 1, the four locking pins 3 are aligned with the four locking holes 101; when the suitcase 2 needs to be used alone, the four rollers 4 of the suitcase 2 are placed on the ground, and the suitcase 2 can be moved alone on the ground.

[0035] Both sets of brake assemblies include a support 8 fixed to the front end of the bottom of the skateboard 1, the lower end of the support 8 is hinged to the lower end of the rocker arm 9, the upper end of the rocker arm 9 is in contact with the skateboard 1, and a tension spring 10 is connected between the side of the middle part of the rocker arm 9 and the skateboard 1. The middle part of the rocker arm 9 is hinged to one end of the connecting rod 11, and the other end of the connecting rod 11 is hinged to the lower end of the brake plate 12. The middle part of the brake plate 12 is rotatably provided on the brake seat 13, and the brake seat 13 is fixed on the corresponding swivel seat 5.

[0036] A pedal 14 is provided at the upper end of the rocker arm 9 of the first brake assembly, a friction wheel 15 is rotatably provided at the upper end of the brake plate 12, a brake wheel 16 for contacting the friction wheel 15 is provided on the rotating shaft 6, a spindle 18 is rotatably provided at the rotation center of the brake plate 12, and two transmission wheels of the transmission mechanism 17 are respectively connected to the rotating shaft of the friction wheel 15 and the spindle 18.

[0037] Among them, the transmission mechanism 17 is composed of two transmission wheels and a transmission belt. The transmission belt is wound around the two transmission wheels at the same time. When one transmission wheel rotates, power is transmitted through the transmission belt to rotate the other transmission wheel.

[0038] The outer side of the friction wheel 15 is made of soft material. The closer the friction wheel 15 is to the brake wheel 16, the more the outer side of the friction wheel 15 is compressed.

[0039] Specifically, during normal travel, the tension spring 10 provides tension, causing the upper end of the rocker arm 9 to contact the skateboard 1. At this point, the friction wheel 15 and brake wheel 1 16 are separated. To brake the skateboard 1, the pedal 14 is depressed, rotating the rocker arm 9 of the first brake assembly. This stretches the tension spring 10, transmitting power through the connecting rod 11, causing the upper end of the brake plate 12 of the first brake assembly to rotate toward brake wheel 1 16. This causes the friction wheel 15 on the brake plate 12 to contact brake wheel 1 16, which in turn drives the friction wheel 15 to rotate. Power is then transmitted through the transmission mechanism 17, causing the spindle 18 to rotate synchronously.

[0040] Two cleaning shafts 19 are rotatably provided at the bottom of the skateboard 1, and cleaning wheel brushes 20 for cleaning the corresponding rollers 4 are respectively provided at both ends of the cleaning shafts 19. The two transmission wheels of the transmission mechanism 21 are respectively connected to the two cleaning shafts 19, and the two transmission wheels of the transmission mechanism 3 22 are respectively connected to a cleaning shaft 19 and the core shaft 18.

[0041] Among them, the working principles of the transmission mechanism 21 and the transmission mechanism 3 22 are consistent with the working principle of the transmission mechanism 1 17.

[0042] Specifically, when the suitcase 2 is placed on the skateboard 1, the four rollers 4 come into contact with the four cleaning brushes 20, respectively. Power is transmitted through transmission mechanism 3 22, causing one cleaning shaft 19 to rotate. Power is then transmitted through transmission mechanism 2 21, causing another cleaning shaft 19 to rotate. As a result, the four cleaning brushes 20 rotate synchronously, driving the rollers 4 with them while simultaneously cleaning the surfaces of the rollers 4. Due to energy loss between the various transmission mechanisms and transmission losses between the cleaning brushes 20 and the rollers 4, the skateboard 1 gradually slows down. Therefore, when the skateboard 1 brakes, the rollers 4 are automatically cleaned, avoiding kinetic energy waste and achieving energy recovery.

[0043] A push plate 23 is provided on the side of the rocker arm 9 of the first brake assembly, and a baffle 24 driven by the push plate 23 is provided on the side of the rocker arm 9 of the second brake assembly, with a gap between the push plate 23 and the baffle 24.

[0044] A brake pad 25 is provided on the upper half surface of the brake plate 12 of the second brake assembly, and a second brake wheel 26 cooperating with the brake pad 25 is provided on the rotating shaft 6 .

[0045] Specifically, when the pedal 14 is stepped on, the pedal 14 drives the rocker arm 9 of the first brake assembly to rotate, and the rocker arm 9 rotates synchronously with the push plate 23. When the push plate 23 contacts the baffle 24, the push plate 23 pushes the baffle 24 to rotate, so the rocker arm 9 of the second brake assembly rotates with the rocker arm 9 of the first brake assembly. Consistent with the working principle of the first brake assembly, the upper half of the brake plate 12 of the second brake assembly moves closer to the brake wheel 26. Even if the brake pad 25 contacts the brake wheel 26, the rotation speed of the rotating shaft 6 decreases rapidly, that is, the skateboard 1 can be braked quickly.

[0046] The bottom of the locking pin 3 is in the shape of a slope, and a locking hole 301 is provided on the side of the locking pin 3 facing the middle. The bottom of the skateboard 1 is located on the side of the lock hole 101 and is provided with a slide 27. A sliding plate 28 for inserting into the locking hole 301 is slidably provided in the slide 27. The sliding plate 28 is provided with a rack 29 on the end face facing the middle. A gear 30 is meshed with between the two racks 29 on each side. A central axis 31 is connected between the two gears 30. The central axis 31 is rotatably provided at the bottom of the skateboard 1, and a spring shaft 32 is connected between the two racks 29 on each side.

[0047] Specifically, when the suitcase 2 is placed on the skateboard 1, the inclined surface of the locking pin 3 contacts the end of the sliding plate 28, causing the sliding plate 28 to slide toward the middle along the slide seat 27, and the spring shaft 32 is compressed. Due to the mutual meshing of the rack 29 and the gear 30, all the racks 29 are ensured to move synchronously. When the locking pin 3 is fully inserted into the corresponding lock hole 101, the lock port 301 coincides with the corresponding sliding plate 28. The spring shaft 32 provides elastic force to move the rack 29 and the sliding plate 28 toward the outside. The sliding plate 28 is inserted into the corresponding lock port 301, and the suitcase 2 is locked on the skateboard 1.

[0048] A middle rod 33 is connected between the two sliding plates 28 near the rear end of the skateboard 1, one end of the rotating plate 1 34 is hinged to the middle part of the middle rod 33, the other end of the rotating plate 1 34 is hinged to one end of the rotating plate 2 35, and the other end of the rotating plate 2 35 is hinged to the end seat 36, the end seat 36 is fixed to the bottom of the skateboard 1, and the rotating plate 2 35 is connected to the unlocking plate 37.

[0049] The second rotating plate 35 is provided with a linkage shaft 38 for driving the brake plates 12 of the second brake assembly.

[0050] Specifically, when the suitcase 2 needs to be removed from the slide 1, the unlocking plate 37 is stepped on to rotate the second rotating plate 35 around the end seat 36, and then the power is transmitted through the first rotating plate 34 to move the middle rod 33 and the corresponding sliding plate 28 toward the middle direction. The power is transmitted through the rack 29 and the gear 30 to move the four sliding plates 28 toward the middle direction at the same time, so that the sliding plates 28 and the corresponding lock ports 301 are separated, and the suitcase 2 and the slide 1 are unlocked.

[0051] A footrest 39 is provided at the front end of the skateboard 1 , and the user steps on the footrest 39 during the running process.

[0052] The front end of the skateboard 1 is also provided with a rotating hole 102, in which a rotating rod 40 is rotatably mounted. A main wheel 41 is provided at the bottom of the rotating rod 40, and a handle 42 is telescopically mounted at the upper end of the rotating rod 40. The extension and contraction of the upper end of the handle 42 is adjusted according to the height of the user. A hub motor is installed inside the main wheel 41, which drives the main wheel 41 to rotate.

[0053] Working principle: When the suitcase 2 needs to be placed on the skateboard 1 for combined use, the four locking pins 3 are aligned with the four locking holes 101. The inclined surface of the locking pin 3 contacts the end of the sliding plate 28, causing the sliding plate 28 to slide toward the middle along the slide seat 27. The spring shaft 32 is compressed. Due to the mutual meshing of the rack 29 and the gear 30, all the racks 29 are ensured to move synchronously. When the locking pin 3 is fully inserted into the corresponding locking hole 101, the lock port 301 coincides with the corresponding sliding plate 28. The spring shaft 32 provides elastic force to move the rack 29 and the sliding plate 28 outward. The sliding plate 28 is inserted into the corresponding lock port 301, and the suitcase 2 is locked on the skateboard 1. At this time, the four rollers 4 are respectively in contact with the four cleaning brushes 20. When in use, the user sits on the suitcase 2, steps on the footrest 39, and adjusts the direction by holding the handle 42. The hub motor inside the skateboard 1 drives the main wheel 41 to rotate, and the two tires 7 rotate accordingly, thereby achieving the purpose of sliding.

[0054] When the luggage case 2 and skateboard 1 are used together and the device is braked, pedal 14 is depressed, which rotates the rocker arm 9 of the first brake assembly. Tension spring 10 stretches, transmitting power through connecting rod 11, causing the upper end of the brake plate 12 of the first brake assembly to rotate toward brake wheel 1 16. This causes friction wheel 15 on brake plate 12 to contact brake wheel 1 16, driving friction wheel 15 to rotate. Power is transmitted through transmission mechanism 1 17, causing spindle 18 to rotate synchronously. Power is transmitted through transmission mechanism 3 22, rotating one cleaning shaft 19. Further power is transmitted through transmission mechanism 2 21, rotating another cleaning shaft 19. This causes four cleaning brushes 20 to rotate synchronously, driving roller 4 with them and cleaning the surface of roller 4. Due to energy losses between the various transmission mechanisms and transmission losses between the cleaning brushes 20 and roller 4, skateboard 1 gradually slows down. Therefore, when the slide plate 1 is braked, the roller 4 is automatically cleaned to avoid kinetic energy waste and complete energy recovery and utilization.

[0055] When rapid braking of the device is required, the pedal 14 is depressed deeply, and the swing arm 9 of the first brake assembly continues to rotate synchronously with the push plate 23. The friction wheel 15 and the first brake wheel 16 come into closer contact, and the outer side of the friction wheel 15 is compressed more. When the push plate 23 contacts the baffle 24, the push plate 23 pushes the baffle 24 to rotate, so the swing arm 9 of the second brake assembly rotates along with the swing arm 9 of the first brake assembly. Similar to the working principle of the first brake assembly, the upper half of the brake plate 12 of the second brake assembly moves closer to the second brake wheel 26. Even if the brake pad 25 contacts the second brake wheel 26, the rotation speed of the rotating shaft 6 is rapidly reduced, and the skateboard 1 can be quickly braked.

[0056] When the suitcase 2 needs to be removed from the slide 1 for separate use, the unlocking plate 37 is stepped on, causing the second rotating plate 35 to rotate about the end seat 36. Then, power is transmitted through the first rotating plate 34, causing the middle rod 33 and the corresponding sliding plate 28 to move toward the middle direction. Power is then transmitted through the rack 29 and the gear 30, causing the four sliding plates 28 to move toward the middle direction simultaneously, thereby separating the sliding plates 28 from the corresponding lock holes 301, and quickly unlocking the suitcase 2 and the slide 1. During this process, the second rotating plate 35 rotates synchronously with the linkage shaft 38. After the linkage shaft 38 contacts the brake plate 12 of the second brake assembly, it drives the brake plate 12 of the second brake assembly to rotate. The upper half of the brake plate 12 of the second brake assembly moves toward the second brake wheel 26, even if the brake pad 25 contacts the second brake wheel 26, thereby limiting the rotation of the second brake wheel 26 and the rotating shaft 6. In this way, the movement of the slide 1 is restricted, making it easier to remove the suitcase 2 from the slide 1.

[0057] When the suitcase 2 is removed from the slide 1, the four rollers 4 of the suitcase 2 are placed on the ground, and the suitcase 2 can be moved on the ground alone. At the same time, the user stands on the top of the suitcase 2 and can use the suitcase 2 as a whole.

[0058] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all within the scope of protection of the present invention.
