Description

Technical Field

[0001] The invention relates to the field of footwear, in particular to an electric shoe comprising a novel brake device. Background Art

[0002] In contemporary society, with the development and progress of transportation, human travel methods have been upgraded and diversified, but walking is still one of the most basic and most commonly used methods, such as shopping, taking subways and buses, working in companies, and activities in living areas. Existing balance bikes have poor safety, and small-wheel electric vehicles and electric scooters are heavy and difficult to fold and store, so they are not suitable to replace walking. At present, there is no safe and convenient single-person transportation tool on the market that can effectively replace walking and provide efficient services for the last kilometer of human travel. Summary of the invention

[0003] In order to improve the walking efficiency of humans in the last kilometer of travel, the inventors have invented an electric shoe including a new brake device after long-term research and experiments in view of the shortcomings and limitations of various existing single-person transportation tools. The new brake device has an ingenious structure and reliable operation, and can more thoroughly solve the problems of walking efficiency and safety, thus helping humans in the last kilometer of travel.

[0004] The present invention specifically adopts the following scheme:

[0005] An electric shoe including a novel brake device comprises a novel brake device, a sole and a shoe body, the novel brake device comprises a brake drive unit, a reset spring, a bridge brake plate and at least one guide column, the sole comprises a sole plate and two groups of shoe wheels arranged front and back, the shoe wheels comprise a fixed shaft and at least one wheel body, the fixed shafts of the two groups of shoe wheels are both fixed on the sole plate, the novel brake device is arranged between the two groups of shoe wheels, the bridge brake plate is located below a line connecting the centers of the two groups of shoe wheels, at least one of the two groups of shoe wheels is a hub-type motor with an outer tire ring, the pull rod of the brake drive unit passes downward through the reset spring and the sole plate and is connected to the bridge brake plate, the guide column is fixed on the sole plate and forms a sliding fit connection with the bridge brake plate.

[0006] Furthermore, the electric shoe including the novel brake device has a built-in control circuit board connected to the brake drive unit and the hub motor, and at least one battery is arranged on the shoe body. The battery is connected to the control circuit board through a wire, and the battery is usually a rechargeable battery that can be recharged repeatedly.

[0007] The hub-type motor is a motor with a stator body in the middle and a rotor body on the outer circumference. The stator shaft is arranged on the central axis of the stator body. The stator shaft is a fixed shaft in the shoe wheel and fixed to the sole plate. The hub-type motor with a tire ring on the outer cover is the shoe wheel that can generate forward driving force. The electric energy of the battery is supplied to the stator body of the hub-type motor through the control circuit board, driving the rotor body to rotate, thereby causing the shoe wheel to rotate and generate forward driving force.

[0008] The function of the guide column is to constrain the movement direction of the bridge brake plate so that the bridge brake plate does not tilt during the braking process.

[0009] A telescopic pad is arranged below the bridge brake plate, and the pull rod continues to extend downward from the bridge brake plate and is connected with the telescopic pad.

[0010] The brake drive unit is a brake motor (10101) or an electromagnet drive component whose rotating shaft is a screw rod.

[0011] The screw rod of the brake motor is an external thread, which forms a spiral transmission with the internal thread of the bridge brake plate. The electric energy of the battery is supplied to the brake motor through the control circuit board to rotate its shaft, so that the bridge brake plate moves upward. When it contacts the front and rear wheel bodies, a braking action is generated, and the screw rod is a pull rod; the screw rod of the brake motor continues to rotate, and because the bridge brake plate is blocked by the two wheel bodies and cannot continue to move upward, the return spring begins to be compressed, causing the brake motor and the screw rod to move downward, driving the telescopic pad to move downward together until the telescopic pad contacts the ground, and the electric shoe containing the new brake device is locked by the bridge brake plate and the telescopic pad in turn. At this time, the wearer can walk and go up and down stairs safely like wearing ordinary shoes, without having to worry about the electric shoes slipping and causing him to fall; the shaft of the brake motor rotates in the opposite direction, the return spring rebounds, and the telescopic pad and the bridge brake plate are unlocked in turn.

[0012] The electromagnet drive assembly comprises an electromagnet and a pull rod (10102), wherein the electromagnet is connected to the pull rod, and the electric energy of the battery is supplied to the electromagnet through the control circuit board to make it attract, thereby driving the pull rod to move upward, and then driving the bridge brake plate connected to the pull rod to move upward, and when it contacts the front and rear sets of wheels, a braking action is also generated; the electromagnet is continuously energized and attracted, driving the pull rod to continue to move upward, and since the bridge brake plate is blocked by the two wheels and cannot continue to move upward, the return spring begins to be compressed, causing the electromagnet and the pull rod to move downward, driving the telescopic pad to move downward together, until the telescopic pad contacts the ground, and the electric shoes containing the new brake device are successively locked by the bridge brake plate and the telescopic pad. At this time, the wearer can also walk and go up and down stairs safely like wearing ordinary shoes; the electromagnet is powered off, the return spring rebounds, and the telescopic pad and the bridge brake plate are also unlocked in turn.

[0013] The shoe sole plate is provided with a bracket for fixing the brake drive unit.

[0014] The electric shoes containing the novel brake device are paired in left and right. The most typical example is that the left and right electric shoes each adopt a structure in which a shoe wheel is arranged at the front and rear, and each shoe wheel is a hub-type motor with a tire ring on the outer cover, and the novel brake device is located between the front and rear shoe wheels.

[0015] At least one pair of mutually attracted cylindrical pins and cylindrical pin sleeves are provided on the inner sides of the left and right sole plates or the left and right shoe bodies. The cylindrical pins and cylindrical pin sleeves are mutually magnetic. When they are close to each other, the cylindrical pins and cylindrical pin sleeves are guided, attracted, and locked. The most typical example is that a pair of mutually attracted cylindrical pins and cylindrical pin sleeves are provided on the inner sides of the left and right sole plates, front and back, respectively.

[0016] The control circuit board has a built-in wireless transmitting module and a wireless receiving module. Accordingly, a wearer of the electric shoes including the novel braking device wears control gloves on the hand joints or control elbow guards on the elbow joints. The control gloves or control elbow guards also have a built-in wireless transmitting module and a wireless receiving module, which are paired and communicated with the built-in wireless transmitting module and the built-in wireless receiving module of the control circuit board, thereby enabling the wearer to control the left and right electric shoes in real time.

[0017] A pressure-sensitive switch, a pressure-sensitive resistor or a pressure-sensitive capacitor connected to a wireless transmitting module is arranged near the joints of the control gloves or the control elbow guards. Through the movement of the hand joints or elbow joints, the wireless transmitting module of the control gloves or the control elbow guards transmits and the wireless receiving module built into the control circuit board of the electric shoes relays, and sends action instructions to the hub motor and the brake motor.

[0018] There are two ways of deceleration and braking: electronically controlled deceleration braking and mechanical deceleration braking. The electronically controlled deceleration is achieved by reducing or stopping the power supply current of the hub motor, or by providing a reverse drive current to the hub motor to achieve deceleration and braking. The mechanical deceleration braking is achieved by supplying power to the brake drive unit of the new brake device to drive the bridge brake plate and telescopic pad to move downward.

[0019] The advantages of the present invention are:

[0020] 1. Compared with the traditional brake device, the new brake device of the present invention has a novel and ingenious structure. It is arranged between the two shoe wheels and can play the dual functions of braking and locking. The wearer can switch safely and freely in various states such as moving, decelerating, turning, braking, walking, etc.; when one of the left shoe and the right shoe accelerates and the other shoe decelerates or brakes, turning can be easily achieved.

[0021] 2. The present invention adopts a hub-type motor, which integrates power and transmission in one, greatly simplifying the overall structure.

[0022] 3. The mutually engaging cylindrical pins and cylindrical pin sleeves provided on the inner side surfaces of the left and right sole plates or the left and right shoe bodies of the present invention can make the left and right shoes lean against each other and be fixed to each other as a whole, so that they can present a stable standing state when charging or storing, thereby facilitating charging or storage.

[0052] The soles 2 of the left shoe and the right shoe both include a sole plate 201 and two sets of shoe wheels 202 .

[0053] The sole plates 201 of the left shoe and the right shoe include two pairs of cylindrical pins 20101 and cylindrical pin sleeves 20102 .

[0054] The shoe wheel 202 includes a fixed shaft 20201 and a wheel body 20202 .

The new brake device 1 of each shoe is arranged between the two sets of shoe wheels 202. The bridge brake plate 103 is located below the line connecting the centers of the two sets of shoe wheels 202. The two sets of shoe wheels 202 of each shoe are hub-type motors with tire rings on the outer shells. The pull rod 10102 of the brake drive unit 101 passes downward through the reset spring 102 and the sole plate 201 and is connected to the bridge brake plate 103. The guide column 104 is fixed on the sole plate 201 and forms a sliding fit connection with the bridge brake plate 103.

[0056] The electric shoe including the novel brake device 1 has a built-in control circuit board connected to the brake drive unit 101 and the hub motor. The battery 301 is connected to the control circuit board via a wire. The battery 301 is a rechargeable battery that can be recharged repeatedly.

[0057] A telescopic pad 105 is arranged below the bridge brake plate 103 , and the pull rod 10102 continues to extend downward from the bridge brake plate 103 and is connected to the telescopic pad 105 .

[0058] The brake drive unit 101 is a brake motor 10101 whose rotating shaft is a screw rod.

[0059] The screw rod of the brake motor 10101 is an external thread, which forms a spiral transmission with the internal thread of the bridge brake plate 103. The electric energy of the battery 301 is supplied to the brake motor 10101 through the control circuit board to rotate the rotating shaft, so that the bridge brake plate 103 moves upward. When it contacts the front and rear wheel bodies 20202, a braking action is generated. The screw rod is the pull rod 10102; the screw rod of the brake motor 10101 continues to rotate.

The cylindrical pins 20101 and cylindrical pin sleeves 20102 are mutually magnetic bodies. When approaching each other, the cylindrical pins 20101 and cylindrical pin sleeves 20102 are guided, attracted, and locked to each other. When charging or storing, the left and right shoes can be leaned against each other and fixed to each other as a whole, and can present a stable standing state, so as to facilitate charging or storage.

[0062] The control circuit board has a built-in wireless transmitting module and a wireless receiving module. Accordingly, a wearer of the electric shoes including the novel braking device wears control gloves on the hand joints or control elbow guards on the elbow joints. The control gloves or control elbow guards also have a built-in wireless transmitting module and a wireless receiving module, which are paired and communicated with the built-in wireless transmitting module and the built-in wireless receiving module of the control circuit board, thereby enabling the wearer to control the left and right electric shoes in real time.

[0063] A pressure-sensitive switch, a pressure-sensitive resistor or a pressure-sensitive capacitor connected to a wireless transmitting module is arranged near the joints of the control gloves or the control elbow guards. Through the movement of the hand joints or elbow joints, the wireless transmitting module of the control gloves or the control elbow guards transmits and the wireless receiving module built into the control circuit board of the electric shoes relays, and sends action instructions to the hub motor and the brake motor.

[0064] The deceleration and braking methods are divided into two types: electronically controlled deceleration braking and mechanical deceleration braking. The electronically controlled deceleration is achieved by reducing or stopping the power supply current of the hub motor, or by providing a reverse drive current to the hub motor to achieve deceleration and braking; the mechanical deceleration braking is achieved by supplying power to the brake motor 10101 of the new brake device 1, driving the bridge brake plate 103 and the telescopic pad 105 to move downward, thereby achieving deceleration and braking.
