[0030] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0031] This application takes into account that skateboarding, as the originator of extreme sports, is loved by many people, and groups of young people gather to skateboard in public places on holidays. In some cases, the skateboard may go out of the skater's control. If the speed was high during the ride, the skateboard may become uncontrollable after "derailing" and cause injury to people around, especially the elderly and children. If the skateboard "derails" on a slope, the danger is even greater due to the acceleration.

[0032] like Figures 1 to 4 As shown in the embodiment of this application, a skateboard is provided, including: a skateboard body 110, the skateboard body 110 including a board surface 111 and a wheel 112 disposed below the board surface 111; a pressure sensor 120 disposed on the board surface 111; and a brake assembly 130 disposed at the bottom of the board surface 111. The pressure sensor 120 is connected to the brake assembly 130 and is used to control the opening or closing of the brake assembly 130. When the brake assembly 130 is open, the brake assembly 130 abuts against the wheel 112.

[0033] The skateboard provided by the embodiment of the present application comprises a skateboard body 110, a pressure sensor 120 and a brake assembly 130. Based on this, during use of the skateboard body 110, a user can stand on the skateboard body 110, and move the skateboard through movement of the wheel body 112. When the skateboard is out of control, the user standing on the skateboard body 110 is separated from the skateboard body 110. In this case, the detection result of the pressure sensor 120 will change, and the brake assembly 130 can be started. The brake assembly 130 is in contact with the wheel body 112 of the skateboard body 110, so as to brake the skateboard, which can greatly reduce the probability of collision between the skateboard and surrounding people, and make the use of the skateboard safer.

[0034] It can be understood that the starting and stopping of the brake assembly 130 can be determined based on the detection result of the pressure sensor 120. For example, if the value of the detection result of the pressure sensor 120 is large, it indicates that a user is standing on the skateboard body 110. In this case, the user can normally operate the skateboard body 110, and even if the skateboard body 110 is out of control, the user can make timely remediation, and the skateboard body 110 is still in a controlled state. Therefore, in this case, the brake assembly 130 is stopped.

[0035] It can be understood that in the case of extreme sports, the skateboard body 110 can be in a state of being in the air. In this case, the user can also be separated from the skateboard body 110. Normally, the brake assembly 130 brakes the wheel body 112, but in this case, the movement of the skateboard body 110 in the air depends on the inertia of the skateboard body 110, that is, even if the skateboard body 110 is in a state of being in the air, it will not affect the normal movement.

[0036] It can be understood that the skateboard provided by the embodiment of the present application is particularly suitable for beginners or small children or young people. When the user can completely control the skateboard, the pressure sensor 120 can be disconnected or the brake assembly 130 can be disassembled. In this case, the brake assembly 130 is not needed to brake the skateboard.

[0037] As shown in FIG. 1, Figures 1 to 4 In a possible implementation, the pressure sensor 120 is a thin-film pressure sensor, and the thin-film pressure sensor is laid on the plate surface 111.

[0038] In the technical solution, the type of the pressure sensor 120 is further provided. The pressure sensor 120 is a thin-film pressure sensor, which has a larger laying area and can better detect whether a user stands on the skateboard body 110.

[0039] It can be understood that the thin film pressure sensor also has the characteristics of simple structure, high sensitivity, wide strategy range, high response efficiency, high reliability and low cost. The thin film pressure sensor is composed of a small amount of materials, has a compact structure and a small size, which makes it suitable for embedded or compact design applications without increasing the thickness of the skateboard. At the same time, its installation is relatively convenient and can be easily integrated into the skateboard. The thin film material responds quickly to pressure changes, has high measurement accuracy and sensitivity. This makes the thin film pressure sensor able to capture small pressure changes and achieve accurate measurement, which is convenient for quickly determining whether someone is standing on the skateboard body 110. The thin film pressure sensor can cover a wide pressure range from a few pascals to tens of megapascals or higher, which is convenient for quickly determining whether someone is standing on the skateboard body 110. Due to the characteristics of the thin film, the thin film pressure sensor has a fast response speed and can monitor and react to external pressure changes in real time. The thin film pressure sensor has no moving parts, a simple structure and no vulnerable parts, so it has high reliability and stability. This makes it able to maintain stable performance during long-term use and reduce maintenance costs. Compared with other types of sensors, the thin film pressure sensor has an advantage in manufacturing cost, which helps to reduce the cost of the skateboard.

[0040] As shown in Figures 1 to 4 In a feasible implementation, the brake assembly 130 includes a steering engine 131 connected below the board surface 111, and an abutting piece 132 connected to the steering engine 131, which abuts with the wheel body 112 in the open state of the brake assembly 130.

[0041] In this technical solution, the structure of the brake assembly 130 is further provided, which can include the steering engine 131 and the abutting piece 132. The swinging of the steering engine 131 can drive the abutting piece 132 to move, and when the abutting piece 132 abuts with the wheel body 112, the brake assembly 130 can brake the wheel body 112. By selecting the steering engine 131, the detection result of the pressure sensor 120 can be responded to, and braking can be quickly performed, making the use of the skateboard safer.

[0042] In a feasible implementation, the abutting piece 132 is made of rubber material, and a stepped surface or a groove is formed on the side of the abutting piece 132 facing the wheel body 112.

[0043] In this technical solution, the style of the abutting piece 132 is further provided, which is made of rubber material and forms a stepped surface or a groove, which is convenient for braking the wheel body 112, has a high friction coefficient, and has a certain deformation ability, which can improve the service life of the skateboard.

[0044] As shown in Figures 1 to 4As shown in a feasible implementation, the skateboard further comprises an energy storage wheel 140 connected to the lower side of the board surface 111 and used to abut against the wheel body 112, and a battery connected to the energy storage wheel 140, the pressure sensor 120 and the brake assembly 130.

[0045] In this technical solution, the skateboard can further comprise the energy storage wheel 140 and the battery. This arrangement is made in consideration of the fact that the skateboard is used independently and thus cannot be connected to a power source or other power source during use. Therefore, when the skateboard is equipped with the brake assembly 130, the skateboard needs to be equipped with a power source. The battery can be used to supply power to the pressure sensor 120 and the brake assembly 130. The energy storage wheel 140 can be used to convert mechanical energy into electrical energy to charge the battery when the wheel body 112 moves. The brake assembly 130 is not started frequently because the skateboard is not out of control frequently. The energy storage wheel 140 can be used to store energy for the battery, which can meet the power demand of the brake assembly 130 and reduce the charging frequency of the battery, thereby making the skateboard more convenient to use.

[0046] In some examples, the skateboard can further comprise a generator 150 connected to the energy storage wheel 1550 and the battery.

[0047] As shown in a feasible implementation, the skateboard further comprises a processor 160. Figures 1 to 4

[0048] In this technical solution, the skateboard can further comprise the processor 160. The pressure sensor 120 is connected to the processor 160, and the processor 160 is connected to the brake assembly 130. Based on this, the processor 160 can control the brake assembly 130 based on the detection result of the pressure sensor 120. That is, when a person stands on the skateboard body 110, the brake assembly 130 does not need to brake the wheel body 112. When the user is separated from the skateboard body 110, the brake assembly 130 can brake the wheel body 112.

[0049] It can be understood that the method of controlling the brake assembly 130 by the processor 160 is a conventional technical means. For example, a first threshold value is set for the pressure sensor 120. When the detection result of the pressure sensor 120 is less than the first threshold value, the brake assembly 130 can be started. This control method is an AND gate control method, which is convenient to implement.

[0050] ​It can be understood that the specific selection of the processor 160 can select the Arduino Uno R3 to use the ATmega328P as the main processor 160, which has high performance and low power consumption. It has 14 digital input / output pins (6 of which can be used as PWM outputs) for connecting various external devices and sensors (D0-D13). It can also be connected to a network module for building smart devices and systems to implement Internet of Things applications.

[0051] In a possible implementation, the skateboard further includes a gyroscope 190 connected to the processor 160 and arranged on the skateboard body 110 to obtain the travel speed of the skateboard body 110.

[0052] In this technical solution, the skateboard can also be equipped with a gyroscope 190. Through the arrangement of the gyroscope 190, the travel speed of the skateboard body 110 can be detected. Based on this, the brake assembly 130 can control the response efficiency of the brake based on the speed result detected by the gyroscope 190. It can be understood that the higher the speed, the higher the brake amplitude and response efficiency should be, which can further improve the safety of the skateboard use.

[0053] It can be understood that the gyroscope 190 is a more preferred technical solution of the present application. In consideration of the cost, the gyroscope 190 can also not be equipped.

[0054] In some examples, the skateboard can also include an acceleration sensor. By arranging the acceleration sensor on the skateboard, the acceleration of the skateboard body 110 can be detected. Based on this, the brake assembly 130 can control the response efficiency of the brake based on the acceleration result detected by the acceleration sensor. It can be understood that the greater the acceleration, the higher the brake amplitude and response efficiency should be, which can further improve the safety of the skateboard use.

[0055] As shown in Figures 1 to 4 In a possible implementation, the skateboard further includes an alarm 170 connected to the processor 160.

[0056] In this technical solution, the skateboard can also include an alarm 170. When the skateboard is in an out-of-control state, the alarm 170 can be turned on. The alarm 170 can alert the surrounding crowd, which can avoid the out-of-control skateboard, and can make the use of the skateboard safer.

[0057] In a possible implementation, the alarm 170 includes a buzzer and / or an alarm light.

[0058] In the technical solution, the type of the alarm 170 is further provided, the alarm 170 can include a buzzer and / or an alarm light, and the surrounding people can be reminded by sound or light, the alarm mode is more eye-catching, and people can quickly find the out-of-control skateboard, thereby reducing the probability of accidents.

[0059] It can be understood that, in the case that the skateboard includes the alarm 170, the skateboard can alarm by the buzzer and / or the light strip in the case of unmanned control; the ultrasonic sensor 180 detects the obstacle in front of the skateboard to brake in an emergency in the case of unmanned control; the gyroscope 190 detects that the speed is too fast to control the brake assembly 130 to brake in the case of unmanned control.

[0060] As shown in FIG. 1, Figures 1 to 4 In a feasible implementation, the skateboard further includes an ultrasonic sensor 180, and the ultrasonic sensor 180 is arranged at the front end of the skateboard body 110.

[0061] In the technical solution, the skateboard can be further provided with the ultrasonic sensor 180, the distance between the skateboard and the front crowd can be detected through the arrangement of the ultrasonic sensor 180, and based on this, the braking amplitude and response efficiency of the brake assembly 130 can be improved when the skateboard is close to the front crowd, so that the use of the skateboard is safer,

[0062] It can be understood that the ultrasonic sensor 180 is a more preferred technical solution, and the ultrasonic sensor 180 can also not be arranged in consideration of the cost.

[0063] It can be understood that the skateboard provided by the embodiment of the application can include various ways of braking by the brake assembly 130, such as point braking or continuous braking.
