Description

Technical Field

[0001] The present invention relates to the technical field of roller skates, in particular to a self-driving roller skate. Background Art

[0002] Roller skates are a kind of sports equipment, which are deeply loved by the public, especially children. However, since ordinary roller skates have no power, they can only be pushed forward by people by constantly lifting their feet and pushing backwards alternately during the sliding process. The small rolling friction of the roller skates can keep the body sliding forward. On the one hand, it is more laborious, and on the other hand, it also increases the difficulty of operation, and requires a more complex training process to master. Electric-driven roller skates can provide a certain driving force, but they need an external power supply and a complex control circuit system, which is also inconvenient to use. Self-driven roller skates can better solve this problem.

[0003] When walking, the body will rise and fall by about ten centimeters. The rising process is the work done by the human body, which raises the center of gravity; the falling process is the work done by gravity, the center of gravity drops, and a downward acceleration is generated, which is then converted into downward kinetic energy. When landing, the downward kinetic energy is superimposed on the function generated by the human body's stepping force, encountering resistance from the ground, and is converted into elastic potential energy of ground deformation and dissipated into the earth. Self-propelled roller skates can convert the kinetic energy of the downward linear motion when the foot steps on the ground into the rotational motion of the wheels in the forward direction. This part of energy can be utilized and converted into the driving force for the roller skates to move forward, which is a very valuable technology.

[0004] Self-driving roller skates use an automatic driving device that cleverly uses the downward kinetic energy of a person's feet when walking to impact the ground, converting it into a forward driving force, generating acceleration for sliding forward, and greatly increasing the walking speed. The driving device is similar to a piston engine, providing power for the wheels. When wearing these roller skates, you only need to walk in a normal gait to generate additional speed on the basis of the normal walking speed. Therefore, it is not only convenient to use and does not require too much complex training to master, but it can also greatly increase the walking speed and achieve the speed effect of running in a normal gait.

[0005] Since this type of roller skates can effectively utilize the pedaling force of the human body and gravity to do work, the drive wheel can be changed to a hub motor drive wheel. In this way, after an external charging circuit and battery are connected, part of the kinetic energy can be converted into electrical energy and stored, which can power electronic equipment when needed.

[0006] Of course, the driving wheel can also be suspended in the air, or even directly replaced by a generator and suspended in the air, so that the roller skates are transformed into a pure power generation shoe. Summary of the invention

[0007] The purpose of the present invention is to provide a self-driving roller skate to solve the above technical problems. Since a set of driving devices is added to the driving wheels of the roller skates, the natural downward stepping action is used to do work during the walking process of the human body, and the driving wheels are rotated in the forward direction, which can increase the forward speed and save time and effort to enjoy the fun of skating. It can not only be used as a sports equipment, but also as an auxiliary tool for daily walking. Without the need for additional power, it can greatly improve the walking speed. Of course, it can also be used as an auxiliary tool for outdoor hiking to improve the walking speed and enrich the travel experience.

[0008] The present invention is achieved through the following technical solutions: A self-propelled roller skate comprises a shoe body, a shoe upper, a shoe sole, a driving unit, an elastic connector, and a fixed connector. The top of the driving unit is connected to the shoe sole of the shoe body, and the driving units can be unconnected, rigidly connected (using a rigid connector), or elastically connected (using an elastic connector) according to needs. When the driving unit is subjected to pressure from the shoe sole, it converts it into a forward driving force to drive the roller skate forward.

[0009] Furthermore, the driving unit includes a piston, a piston sleeve, a connecting rod, a ratchet, a transmission device, a driving wheel, and a bracket. The bracket includes an upper plane of the bracket, a lower plane of the bracket, a spring (group), and a support frame. The upper plane of the bracket and the lower plane of the bracket are connected together by a spring (group), and the lower part of the lower plane of the bracket is connected to the support frame. The piston is installed on the upper plane of the bracket, the direction is downward (the entity is below the upper plane), and the piston sleeve is installed on the lower plane of the bracket, the direction is downward (the entity is below the lower plane), and the positions of the two are corresponding. The ratchet, the transmission device, and the driving wheel are installed on the support frame. The connecting rod connects the lower end of the piston and the driving wheel of the ratchet (the connection point is close to the circumference on the driving wheel) to form a crankshaft connecting rod structure. The driven wheel of the ratchet is connected to the driving wheel through the transmission device to transmit power to the driving wheel. When not in use, the spring (group) is in an expanded state, and a certain distance is maintained between the upper and lower planes of the bracket. When walking, when you step on the sole of the shoe, the spring is compressed, the piston of the drive unit is under pressure, and moves downward to do work; when you lift your foot, the spring returns to its original position, and the piston moves upward to return to its original state. This cycle repeats, and work continues to be done to provide power.

[0010] Furthermore, the transmission device includes a ratchet driven wheel, a transmission gear, and a driving wheel. The outer edge of the ratchet driven wheel is provided with a gear, the transmission gear and the ratchet driven wheel are connected to each other through the gear, the driving wheel and the transmission gear are coaxial, and the wheel bodies are fixed together. The transmission gear is a small gear that can generate a rotation speed several times that of the ratchet driven wheel. Because the driving wheel and the transmission gear are fixed together, a high-speed forward rotation speed is also generated.

[0011] Furthermore, a sliding guide rail is provided between the upper plane and the lower plane of the bracket to enhance the stability and smoothness of the relative movement of the upper and lower planes.

[0012] Further, the sliding guide rail is provided with a limit piston and a limit piston sleeve respectively between the upper plane and the lower plane of the bracket, the limit piston is installed on the upper plane of the bracket, the direction is downward (the entity is below the upper plane), and the limit piston sleeve is installed on the lower plane of the bracket, the direction is downward (the entity is below the lower plane), and its position corresponds to the limit piston. The limit piston / limit piston sleeve can be provided in one or more groups.

[0013] Furthermore, the springs of the spring (group) can be arranged independently, or can be arranged to be sleeved on the outside of the piston, or can be arranged to be sleeved on the outside of the limit piston to form a compact structure.

[0014] Furthermore, in order to prevent the connecting rod mechanism from failing at the dead point (the farthest end and the closest end of the connecting rod movement) during operation and causing reverse rotation without work, the piston stroke is set so that when the connecting rod drives the ratchet driving wheel, the driving wheel reciprocates between the two dead points. In this case, the driving wheel rotates less than 180 degrees. The driven wheel of the ratchet rotates continuously in one direction under intermittent drive.

[0015] Furthermore, the driving wheel can adopt a hub motor and be externally connected to a battery and a charging circuit. When sliding forward, part of the kinetic energy can be converted into electrical energy and stored, and can be used to supply power to electronic devices when needed.

[0016] Furthermore, the support frame can be extended to contact the ground, and the drive wheel using the hub motor can be suspended in the air, so that the kinetic energy of the drive device is all used for power generation, and the roller skates are transformed into pure power generation shoes. Of course, the drive wheel can also be directly replaced by a generator.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The present invention is further described herein with reference to three embodiments.

[0026] The first embodiment of the present invention is Figure 1 As shown, a self-propelled roller skate is provided, including a shoe body 10, an upper 110, a sole 120, a driving unit 130, an elastic connector 141, and a fixed connector 142.

[0027] The sole 120 is connected to the upper 110, and the driving unit 130 is connected to the sole 120. The driving units are connected to each other (including front and back and left and right) through the elastic connector 141 and the fixed connector 142, or they may not be connected.

[0028] In this embodiment, when the driving unit 130 receives pressure from the sole 120, it converts the pressure into a forward driving force to drive the roller skates to move forward.

[0029] The structure of the self-driving roller skate driving unit of the present invention is as follows: Figure 2 As shown, it includes a piston 1311, a piston sleeve 1312, a connecting rod 132, a ratchet driving wheel 1331, a ratchet driven wheel 1332, a transmission gear 134, a driving wheel 135, a bracket 136, an upper plane 1361 of the bracket, a lower plane 1362 of the bracket, a spring (group) 1363, a limiting piston 1364, a limiting piston sleeve 1365, and a supporting frame 1366.

[0030] The bracket upper plane 1361 and the bracket lower plane 1362 are basically arranged horizontally, and a spring (group) 1363 is arranged between the two to connect them. The support frame 1366 is connected to the bracket lower plane 1362 and is arranged below the bracket lower plane 1362. The limit piston 1364 is installed on the bracket upper plane 1361, and the direction is downward. The limit piston sleeve 1365 is installed on the bracket lower plane 1362, and the direction is downward. Its position corresponds to the limit piston 1364. The limit piston / limit piston sleeve can be provided in one or more groups.

[0031] The piston 1311 is mounted on the upper plane 1361 of the bracket, in a downward direction (the entity is below the upper plane), and the piston sleeve 1312 is mounted on the lower plane 1362 of the bracket, in a downward direction (the entity is below the lower plane), and the two positions correspond to each other. The connecting rod 132 connects the lower end of the piston and the ratchet driving wheel 1331 (the connection point is on the wheel near the circumference), forming a crankshaft connecting rod structure. The outer edge of the ratchet driven wheel 1332 is provided with a gear, and the transmission gear 134 forms a transmission connection with the ratchet driven wheel 1332 through the gear, and the driving wheel 135 is coaxial with the transmission gear 134, and the wheel bodies are fixed together. The ratchet driving wheel 1331, the ratchet driven wheel 1332, the transmission gear 134, and the driving wheel 135 are mounted on the supporting frame 1366 through their respective axes.

[0032] The springs of the spring (group) 1363 can be independently arranged, or can be arranged to be sleeved on the outside of the piston 1311, or can be arranged to be sleeved on the outside of the limiting piston 1364 to form a compact structure.

[0033] In this embodiment, the position setting requirements of the piston 1311, the connecting rod 132, and the ratchet driving wheel 1331 are, firstly, to ensure that the driving force in the forward direction is provided when the piston moves downward, and secondly, to ensure that the connecting rod reciprocates between the two dead points of the crankshaft connecting rod structure. In this way, the ratchet driving wheel will reciprocate less than 180 degrees, which can prevent the ratchet from reversing at the dead point.

[0034] In this embodiment, when the human body steps down, the upper plane 1361 of the bracket moves downward under pressure, driving the piston 1311 to move, driving the ratchet driving wheel 1331 to make a circular motion through the connecting rod 132, and the ratchet driving wheel 1331 drives the ratchet driven wheel 1332 to rotate, thereby driving the transmission gear 134 to rotate, and the transmission gear 134 drives the driving wheel 135 to move, so as to achieve the effect of the roller skates moving forward. When the foot is lifted, the pressure on the upper plane 1361 of the bracket disappears, and under the elastic force of the spring (group) 1363, it moves upward, driving the piston 1311, the connecting rod 132 and the ratchet driving wheel 1331 to reset, and the ratchet driven wheel 1332, the transmission gear 134, and the driving wheel 135 continue to make inertial motion.

[0035] The self-driving roller skate driving units of the present invention are rigidly connected to each other. Figure 3 As shown, it includes a driving unit 130 and a rigid connecting member 141.

[0036] The driving units 130 may be connected together front to back and left to right via a rigid connector 141 to enhance overall stability.

[0037] The self-driving roller skate driving units of the present invention are elastically connected to each other. Figure 4As shown, it includes a driving unit 130 and an elastic connecting member 142.

[0038] The drive units 130 can be connected together front to back and left to right by elastic connectors 142 to enhance overall stability. At the same time, when the sole is deformed during walking, the relative positions of the drive units can be properly followed at any time to improve the applicability of the product.

[0039] The second embodiment of the present invention is Figure 5 As shown, a self-propelled roller skate with power generation function is provided. On the basis of the first embodiment, charging and discharging components are added, including a battery 151 and a charging circuit 152.

[0040] The battery 151 and the charging circuit 152 are mounted on the shoe body 10, and the driving wheel 135 has a hub motor. A portion of the kinetic energy of the driving wheel 135 can be converted into electrical energy by the hub motor, and charged to the battery 151 by the charging circuit 152 for storage, and can be used to power other electronic devices when needed.

[0041] The third embodiment of the present invention is Figure 6 As shown, a power generating shoe based on the principle of self-propelled roller skates is provided. On the basis of the second embodiment, some components are modified, including a supporting frame 1366 and a driving wheel 135.

[0042] The support frame 1366 extends downward, contacts the ground to form a support surface, and the driving wheel 135 is suspended in the air, and the roller skates become a pure power generation shoe. At this time, the driving wheel 135 can also be replaced by a generator.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
