Description

Technical Field

[0001] This invention belongs to the aerospace field, specifically relating to a low-power electromagnetic locking separation shoe for use in zero-gravity or microgravity environments, suitable for walking in zero-gravity (microgravity) environments. Background Technology

[0002] With the continuous development of space technology and the increasing maturity of spacecraft, exemplified by space stations, the scenarios and conditions for humans to work in zero (or micro) gravity environments are becoming more and more common. Currently, astronauts from various countries generally achieve walking in zero (or micro) gravity environments by using looped ropes arranged at the bottom of the spacecraft, or by using electromagnetic forces. Specifically, the method of using looped ropes at the bottom of the spacecraft involves hooking the feet onto the looped ropes and moving by the interaction between the body and the ropes. The biggest problem with this method is that the flexibility of the ropes and the magnitude of the force are difficult to control, making it difficult to control the body's posture and maintain a balance consistent with the spacecraft. In methods for achieving walking in a weightless (micro)gravity environment using electromagnetic force, attraction to ferromagnetic materials is achieved by energizing the electromagnet core of an integrated coil. This requires the electromagnetic coil assembly to be continuously energized. However, if the current is too small, the attraction force is weak; if the current is too large, continuous energization will result in significant power loss and heat generation. This method leads to poor reliability of the electromagnetic shoe and places high demands on the power supply system. To provide a larger electromagnetic attraction force, the volume of the electromagnet core and coil must increase, resulting in an increase in overall weight. Furthermore, when the electromagnetic coil assembly is energized, it will continuously generate electromagnetic radiation and interference to the outside world, thus failing to meet the requirements of lightweight, low power consumption, and low magnetic leakage. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects and provide a low-power electromagnetic locking separation shoe for zero-gravity or microgravity environments. This invention solves the technical problems that traditional electromagnetic shoes cannot meet the requirements of lightweight, low power consumption, and low magnetic leakage. The electromagnetic locking separation shoe of this invention has a simple structural design and is lightweight; it is driven by pulse voltage, resulting in low power consumption; and when in the locking or separating state, the magnetic circuit is closed, resulting in low magnetic leakage.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0005] A low-power electromagnetic locking separation shoe for zero-gravity or microgravity environments includes a magnetic pad, an electromagnetic locking separation device, a shoe sole, and a shoe upper.

[0006] The boot upper and sole combine to form the boot body;

[0007] The boot sole has two cavities inside the front and rear ends, and each cavity is equipped with an electromagnetic locking and separation device.

[0008] The electromagnetic locking and separating device includes a fixed iron core group, a moving iron core group, and an electromagnetic group. The fixed iron core group and the electromagnetic group are fixedly connected to the shoe bottom, and the moving iron core group is located between the fixed iron core group and the electromagnetic group, and the moving iron core group is slidably connected to the shoe bottom. When the electromagnetic group is energized, it pushes the moving iron core group to make it fit with the fixed iron core group, or pulls the moving iron core group to make it fit with the electromagnetic group, thereby locking or separating the shoe body from the magnetic pad.

[0009] Furthermore, the fixed iron core assembly includes two iron cores I, each of which is a cube;

[0010] The electromagnetic assembly includes iron core II, a frame, and an electromagnetic coil. Iron core II is U-shaped with its opening facing the moving iron core assembly. The electromagnetic coil is fitted around the outside of iron core II using the frame.

[0011] The moving iron core assembly includes iron core III and permanent magnet. Both iron core III and permanent magnet are elongated strips. The two ends of the permanent magnet are connected to two iron cores III respectively, and the length direction of the permanent magnet is perpendicular to the length direction of iron core III.

[0012] When the first ends of the two iron cores III are in contact with the two iron cores I, and the second ends of the two iron cores III are separated from the two ends of the iron core II, the boot body is locked to the magnetic pad; when the first ends of the two iron cores III are separated from the two iron cores I, and the second ends of the two iron cores III are in contact with the two ends of the iron core II, the boot body is separated from the magnetic pad.

[0013] Furthermore, the two cavities at the front and rear ends of the boot sole are referred to as the front cavity and the rear cavity, respectively. The bottom of the front cavity and the rear cavity are provided with openings, and the iron core I interacts with the magnetic pad through the openings.

[0014] Furthermore, the bottom of the front cavity and the rear cavity are provided with sliding grooves for engaging with the iron core III.

[0015] Furthermore, stress sensor units for detecting walking motions are distributed on the upper surface of the boot sole and the inner surface of the boot upper.

[0016] Furthermore, an intermediate cavity is provided between the front cavity and the rear cavity of the boot sole;

[0017] The middle cavity, the front cavity, and the rear cavity are independent of each other;

[0018] The middle cavity contains an integrated circuit unit, a battery unit, and a wireless charging unit.

[0019] Furthermore, the middle cavity is T-shaped, and the upper surface of the middle cavity is the upper surface of the boot sole; the front cavity and the rear cavity are detachable structures, and the front cavity and the rear cavity are respectively assembled to the front end and the rear end of the middle cavity to form the boot sole.

[0020] Furthermore, the magnetic pad has a planar structure.

[0021] Furthermore, the bottom of the intermediate cavity is provided with inlet and outlet slots leading to the electromagnetic locking separation device;

[0022] The stress sensor unit connects the signal to the integrated circuit unit.

[0023] Furthermore, the integrated circuit unit includes a controller unit, a chip and memory unit, and a wireless signal transceiver unit;

[0024] The chip and storage unit are used to receive signals from the stress sensor unit, determine the walking action based on the signals, and send instructions to the controller unit based on the determination of the walking action.

[0025] The controller unit controls the battery unit to send pulse signal commands to the electromagnetic assembly according to the instructions;

[0026] The wireless transceiver unit is used to receive a forced power-off command from an external signal generator when a locked state needs to be maintained for an extended period.

[0027] Compared with the prior art, the present invention has at least one of the following advantages:

[0028] (1) This invention creatively proposes a low-power electromagnetic locking separation shoe, which can achieve electromagnetic locking and separation with the magnetic pad through an electromagnetic locking separation device;

[0029] (2) The low-power electromagnetic locking separation shoe designed in this invention has a simple structure, is lightweight, and is easy to implement;

[0030] (3) The low-power electromagnetic locking separation shoe designed in this invention uses short pulse voltage to realize the electromagnetic locking and separation of the electromagnetic locking separation device and the magnetic pad, without the need for long-term power supply, thus the power consumption is low;

[0031] (4) The low-power electromagnetic locking separation shoe designed in this invention has a closed internal magnetic circuit structure when the electromagnetic locking separation device is attracted or separated from the magnetic pad, with extremely low leakage magnetic field and no interference to other electronic devices.

[0051] The features and advantages of the present invention will become clearer and more apparent from the following detailed description.

[0052] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0053] This invention provides a low-power electromagnetic locking separation shoe for use in zero (micro)gravity environments, suitable for walking in zero (micro)gravity environments.

[0054] This invention discloses a low-power electromagnetic locking and separation shoe for use in zero (micro)gravity environments, comprising a magnetic pad, an electromagnetic locking and separation device, a shoe sole, and a shoe upper. The electromagnetic locking and separation device includes a fixed iron core assembly, a moving iron core assembly, and an electromagnetic assembly, installed at the front and rear of the shoe sole; the magnetic pad is planar; the shoe sole is elliptical, with its bottom surface in contact with the magnetic pad; the shoe upper surrounds the outer edge of the upper surface of the shoe sole and is connected to the shoe sole, with the cavity opening located in the rear half of the shoe body.

[0055] The fixed iron core assembly, the moving iron core assembly, and the electromagnetic assembly are installed in the front and rear cavities of the boot sole. The fixed iron core assembly includes two iron cores I, one end of which is flat and flush with the bottom surface of the boot sole. The electromagnetic assembly includes iron core II, a frame, and an electromagnetic coil. The frame is placed on iron core II, and the electromagnetic coil is placed on the frame.

[0059] An integrated circuit unit includes a controller unit, a chip and storage unit, and a wireless signal transceiver unit.

[0060] Example:

[0061] The electromagnetic locking separation boot in this invention has the following appearance: Figure 1 As shown. Figure 1 As shown, the electromagnetic locking separation boot of the present invention includes a magnetic pad 1, an electromagnetic locking separation device 2, a boot sole 3, and a boot upper 4. Figure 8 The electromagnetic locking and separating device 2 includes a fixed iron core assembly 5, a moving iron core assembly 6, and an electromagnetic assembly 7, installed in the front cavity 301 and rear cavity 302 of the boot sole. The lower surfaces of the front cavity and rear cavity are flush with the lower surface of the intermediate cavity, and the three together form the lower surface 303 of the boot sole; the magnetic pad 1 is planar; as Figure 6 The boot sole 3 is oval-shaped (equivalent to a regular shoe sole), and the lower surface 303 of the boot sole is either attached to or separated from the magnetic pad 1; for example... Figure 7 The upper 4 (equivalent to a regular shoe upper) surrounds the outer edge of the upper surface 304 of the boot sole and is connected to the boot sole 3. The cavity opening 401 is located at the rear of the boot body composed of the boot sole 3 and the upper 4.

[0062] like Figure 2 , Figure 3 and Figure 4 The fixed iron core assembly 5, the moving iron core assembly 6, and the electromagnetic assembly 7 are installed in the front cavity and the rear cavity, respectively. The fixed iron core assembly 5 includes two iron cores I9, such as... Figure 9 The lower end face of iron core I9 is ​​flat and flush with the lower surface 303 of the boot bottom, meaning the lower end face of iron core I9 is ​​exposed and can directly contact the magnetic pad 1; the electromagnetic assembly 7 includes, for example, Figure 10 Iron core II10, such as Figure 11 11. The skeleton, such as Figure 12 The electromagnetic coil 12 is placed on the frame 11, and the frame 11 is placed on the iron core II 10. The moving iron core assembly 6 includes two elongated iron cores III 13 and a permanent magnet 14, such as... Figure 14 The permanent magnet 14 connects two iron cores Ⅲ 13 and is located in the middle 1301 of iron core Ⅲ, as shown below. Figure 13 ;like Figure 5 The lower surfaces of the front cavity and the rear cavity have openings 803 that match the lower end face of the iron core I, and the lower surfaces of the front cavity and the rear cavity are provided with sliding grooves 804 that match the shape of the iron core III, so as to facilitate the sliding of the iron core III 13.

[0063] like Figure 15 The intermediate cavity of the boot sole 3 contains an integrated circuit unit 15, a battery unit 16, and a wireless charging unit 17. The intermediate cavity includes a downward-facing groove 307 and a cover plate 18 that mates with the groove. The bottom of the groove 307 has an inlet / outlet slot 308 leading to the electromagnetic locking separation device 2. The integrated circuit unit 15, the battery unit 16, and the wireless charging unit 17 are placed in the groove 307, and the cover plate 18 is fixed above the groove, forming the upper surface 304 of the boot sole.

[0064] like Figure 16 and Figure 17 Stress sensor units 19 are distributed on the boot body. The stress sensor units are located at the middle and sides of the front and rear of the upper surface of the boot sole, as well as at the front end 402 and the rear end 403 of the boot surface. The stress sensor units connect the signals to the integrated circuit unit 15 through the base.

[0065] like Figure 18 The integrated circuit unit 15 includes a controller unit 20, a chip and storage unit 21, and a wireless signal transceiver unit 22.

[0066] In this invention, the electromagnetic locking separation shoe applies a pulse signal to the electromagnetic group 7 in the electromagnetic locking separation device 2. Driven by electromagnetic force, the permanent magnet 14 is pushed away from or closer to the electromagnetic group 7, thereby causing the moving iron core group 6 to move away from or closer to the electromagnetic group 7. When the moving iron core group 6 is attached to the electromagnetic group 7, the moving iron core group 6 and the electromagnetic group 7 form a closed magnetic circuit. At this time, the magnetic circuit between the fixed iron core group 5 and the magnetic guide pad 1 is broken, and there is no electromagnetic attraction between the electromagnetic locking separation device 2 and the magnetic guide pad 1. When the moving iron core group 6 is attached to the fixed iron core group 5, the moving iron core group 6 and the fixed iron core group 5 form a closed magnetic circuit. At this time, the magnetic circuit between the fixed iron core group 5 and the magnetic guide pad 1 is closed, and the electromagnetic locking separation device 2 and the magnetic guide pad 1 generate an electromagnetic attraction, breaking the magnetic circuit between the moving iron core group 6 and the electromagnetic group 7.

[0067] The battery unit 16 provides power to the entire electromagnetic locking release shoe, and the battery unit 16 can be replenished through the wireless charging unit 17.

[0068] When in a zero (micro) gravity environment, a human can wear two electromagnetic locking and separating boots of the present invention. The magnetic pad 1 is laid on the walking surface in the zero (micro) gravity environment. The mechanical sensors on the sole 3 and upper 4 of the boot transmit data to the chip and storage unit 21 in the integrated circuit unit 15 through the walking action of the human feet in the zero (micro) gravity environment. The chip and storage unit make intelligent judgments based on the results of the user's previous deep training and learning, and issue instructions to the controller unit 20. The controller unit 20 sends pulse signal instructions to the electromagnetic group 7 to realize the locking and separating functions of the electromagnetic locking and separating device 2.

[0069] Meanwhile, depending on the user's operating conditions, when the user needs to keep the electromagnetic locking separation device 2 and the magnetic pad 1 in a state of attraction for a long time, the user can send a command to the wireless signal transceiver unit 22 through an external signal generator to force the non-power-on command, so that the electromagnetic locking separation device 2 and the magnetic pad 1 are always in a state of attraction.

[0070] Compared with ordinary shoe uppers, the boot upper 4 in this invention has higher strength and is not easily deformed. When the user's electromagnetic locking separation device 2 and magnetic pad 1 are always in an attractive state, when the user's posture changes in a zero (micro)gravity environment, the sensors on both sides of the upper surface of the boot and the sensors on both sides of the boot upper are under force. Combined with the results of the user's previous deep training and learning, intelligent judgment is made so that the electromagnetic locking separation device 2 and magnetic pad 1 are always in an attractive state. The user corrects his posture through the interaction between his own foot and the boot upper.

[0071] The present invention has been described in detail above with reference to specific embodiments and exemplary examples; however, these descriptions should not be construed as limiting the present invention. Those skilled in the art will understand that various equivalent substitutions, modifications, or improvements can be made to the technical solutions and embodiments of the present invention without departing from the spirit and scope of the invention, and all such modifications and improvements fall within the scope of the present invention.
